IP Geolocation

Targeted Online Advertising by Country using .NET Framework in VB.NET or C#

noreply@blogger.com (Unknown) — Thu, 19 Nov 2009 04:19:00 +0000

The global nature of websites is such that to maximize your earnings from online advertisements, you have to display different advertisements for visitors from different countries. This way, your web visitors will only see advertisements that are relevant to their country and thus be more inclined to click on those advertisements. In the long term, this will help to boost your revenue from the advertisements.

In this example, we will use a fully functional IP2Location™ .NET component available at http://www.ip2location.net/download/IP2LocationDotNetComponent.ZIP to determine the visitor’s country by their IP address. Firstly, install the IP2Location™ .NET component. Once installation is complete, get the IP2Location.DLL .NET component and sample database from the directory, i.e. C:\Program Files\IP2Location by default. You need to add a reference to this component from your Visual Studio web project. A copy of this component will be copied into /bin directory under the project. If the component is unregistered, there is a random 5-second delay in one out of ten queries.

To avoid any delays in the query, you can consider purchasing the IP2Location™ .NET Component Version 3.0, which is a software development component and data solution for .NET Framework. You can then dynamically tailor the content of your site based on your visitors country, region, city, latitude, longitude, ZIP code, ISP, domain name, timezone, connection speed, IDD code, area code, weather statation code, and weather station name.

Below is the sample code in VB.NET and C# webform which will display the targeted online advertising by country.

Sample Codes in VB.NET Webform

Imports IP2Location
Private Sub Query(ByVal strIPAddress As String)
    Dim oIPResult As New IP2Location.IPResult

    Try
        If strIPAddress <> "" Then
            IP2Location.Component.IPDatabasePath = "C:\\Program Files\\IP2Location\\Database\\IP-COUNTRY.SAMPLE.BIN"
            oIPResult = IP2Location.Component.IPQuery(strIPAddress)

            Select Case oIPResult.Status
                Case "OK"
                    If oIPResult.CountryShort = "JP" Then
                        ' Visitor is from Japan
                        ' Show advertisement from JP
                        Response.Write "<img src=""Japan.jpg"" border=""0"" height=""200"" width=""100"" />"
                    Else
                        ' Visitor is not from Japan
                        ' Show other advertisement
                        Response.Write "<img src=""US.jpg"" border=""0"" height=""200"" width=""100"" />"
                    End If
                Case "EMPTY_IP_ADDRESS"

                Case "MISSING_FILE"
                    Response.Write("Invalid Database Path.")
            End Select
        Else
            Response.Write("IP Address cannot be blank.")
        End If
    Catch ex As Exception

    Finally
        oIPResult = Nothing
    End Try
End Sub

Sample Codes in C# Webform

Using IP2Location;
private void Query(string strIPAddress)

Optimize Online Advertising Campaign by Country using PHP and MySQL Database

noreply@blogger.com (Unknown) — Thu, 19 Nov 2009 03:45:00 +0000

Let’s say you are coming from an English speaking country and you visit a website that shows you advertisements in a foreign language that you don’t understand. You would just ignore those advertisements like any normal person would. To the website owner, this is a lost opportunity to earn some money. That is why it is so vital to be able to match your web visitors with online advertisements that they will find relevant and useful. One way to do this is to show one set of advertisements for visitors from one country and then show another set to visitors from another country.

In this tutorial, we will use the IP2Location™IP-Country database to determine the country of origin for the web visitor just by checking the IP address. Instead of loading the full database with 50000+ records, we could simplify this tutorial with the assumption that only two different IP address ranges in the world. IP addresses of the range 0.0.0.0 - 126.255.255.255 originates from the United States. Meanwhile, IP addresses of the range 127.0.0.0 - 255.255.255.255 originates from Japan. Here we are creating a database called "IP2Location" with a table called "IPCountry" which contains our two IP address range records.

Step 1: Start the mysql command prompt. Run the 2 SQL command below to create the ‘IP2Location’ database and select it for use.

mysql> CREATE DATABASE IP2Location
mysql> CONNECT IP2Location

Step 2: Next, run the SQL statement below to create the ‘IPCountry’ table.

mysql> CREATE TABLE IPCountry
--> (
--> ipFROM DOUBLE NOT NULL,
--> ipTO DOUBLE NOT NULL,
--> countrySHORT VARCHAR(2) NOT NULL,
--> countryLONG VARCHAR(100) NOT NULL,
--> PRIMARY KEY(ipFROM, ipTO)
--> );

Step 3: Run the SQL codes below to insert dummy data into the database.

mysql> INSERT INTO IPCountry VALUES (0, 2130706431,'US','UNITED STATES');
mysql> INSERT INTO IPCountry VALUES (2130706432, 4294967295,'JP','JAPAN');

The full version of IP-Country database is available for subscription at $49/year from http://www.ip2location.com/ip-country.aspx.

If you have the full version of IP2Location™IP-Country database, the import process is easier by using the LOAD DATA feature available in MYSQL.

PC:
mysql> LOAD DATA INFILE "/IPCountry.csv" INTO TABLE IPCountry FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';

Linux/Unix:
mysql> LOAD DATA INFILE "/IPCountry.csv" INTO TABLE IPCountry FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n';

Below is a sample code in PHP which will show you how to use the data to optimize your online advertising campaign by country.

<%php
// Replace this MYSQL server variables with actual configuration
$mysql_server = "mysql_server.com";
$mysql_user_name = "UserName";
$mysql_user_pass = "Password";

// Retrieve visitor IP address from server variable REMOTE_ADDR
$ipaddress = getenv(REMOTE_ADDR);

// Convert IP address to IP number for querying database
$ipno = Dot2LongIP($ipaddress);

// Connect to the database server
$link = mysql_connect($mysql_server, $mysql_user_name, $mysql_user_pass) or die("Could not connect to MySQL database");

// Connect to the IP2Location database
mysql_select_db("IP2Location") or die("Could not select database");

// SQL query string to match the recordset that the IP number fall between the valid range
$query = "SELECT * FROM IPCountry WHERE $ipno <= ipTO AND $ipno>=ipFROM";

// Execute SQL query
$result = mysql_query($query) or die("IP2Location Query Failed");

// Retrieve the recordset (only one)
$row = mysql_fetch_object($result);

// Keep the country information into two different variables
$countrySHORT = $row->countrySHORT;
$countryLONG = $row->countryLONG;

// Free recordset and close database connection
mysql_free_result($result); mysql_close($link);

if ($countrySHORT == "JP")
{
// If the visitors are from JP, show advertisement from JP
echo "<img src="Japan.jpg" border="0" height="200" width="100">";
}
else {
// Otherwise, show other advertisement
echo "<img src="US.jpg" border="0" height="200" width="100">";
}
exit;

// Function to convert IP address (xxx.xxx.xxx.xxx) to IP number (0 to 256^4-1)
function Dot2LongIP ($IPaddr) {
if ($IPaddr == "")
{
return 0;
} else {
$ips = split ("\.", "$IPaddr");
return ($ips[3] + $ips[2] * 256 + $ips[1] * 256 * 256 + $ips[0] * 256 * 256 * 256);
}
}
%>

Niche Advertising by Country using ASP and MS-SQL Database

noreply@blogger.com (Unknown) — Thu, 19 Nov 2009 03:05:00 +0000

Online advertisements are a big revenue earner for most websites. So it is no wonder that most of them employ ways to detect their web visitor’s country so that the advertisements can be targeted to its niche audience. By doing so, the probability of a sale from the online advertisement increases tremendously as the targeted audience would most likely find that advertisement to be relevant and maybe even helpful.

In this tutorial, we will use the IP2Location™IP-Country database to determine the country of origin for the web visitor just by checking the IP address. Instead of loading the full database with 50000+ records, we could simplify this tutorial with the assumption that only two different IP address ranges in the world. IP addresses of the range 0.0.0.0 - 126.255.255.255 originates from the United States. Meanwhile, IP addresses of the range 127.0.0.0 - 255.255.255.255 originates from Japan. Here we are creating a database called "IP2Location" with a table called "IPCountry" which contains our two IP address range records.

Step 1: Start Microsoft SQL Server Management Studio.

Now, login to your database instance and then click on the New Query button. Copy the 2 lines of SQL codes below into the query window and press Execute to run the codes. This will create the ‘IP2Location’ database and select it for use.

CREATE DATABASE IP2Location
GO
USE IP2Location
GO

Step 2: Next, run the SQL statement below to create the ‘IPCountry’ table.

CREATE TABLE[dbo].[IPCountry] (
[ipFROM] [float] NOTNULL ,
[ipTO] [float] NOT NULL ,
[countrySHORT] [nvarchar] (2),
[countryLONG] [nvarchar] (64)
) ON [PRIMARY]
GO

Step 3: Run the SQL codes below to insert dummy data into the database.

INSERT INTO IPCountry VALUES (0, 2130706431,'US','UNITED STATES');
INSERT INTO IPCountry VALUES (2130706432, 4294967295,'JP','JAPAN');

The full version of IP-Country database is available for subscription at $49/year from http://www.ip2location.com/ip-country.aspx. If you have the full version of IP2Location™IP-Country database, import process is easy done by using the Database Transformation Service (DTS) in MS-SQL.

In your ASP page, you will need to put in the codes below.

<%
Dim conn, myDSN, mySQL, rs

' SQL database connection. NOTE: Replace servername, username and password to your own values.
Set conn = Server.CreateObject("ADODB.Connection")

myDSN="DRIVER={SQLServer};SERVER=servername;UID=username;PWD=password;DATABASE=IP2Location"

conn.open myDNS

' retrieve visitor IP address and translate it to IP address number
IPno = Dot2LongIP(Request.ServerVariables("REMOTE_ADDR"))

' SQL query to lookup valid range of IP address
mySQL = "SELECT countrySHORT FROM IPCountry WHERE " & IPno & " BETWEEN ipFROM AND ipTO"

Set rs = Server.CreateObject("ADODB.Recordset")
rs.open mySQL, conn

' assign country name for reference
countryName = rs("countrySHORT")

' close and free connections

' Show other advertisement
response.write "<img src=""US.jpg"" border=""0"" height=""200"" width=""100"">"
End If
%>

Function Dot2LongIP (ByVal DottedIP)
Dim i, pos
Dim PrevPos, num
If DottedIP = "" Then
Dot2LongIP = 0
Else
For i = 1 To 4
pos = InStr(PrevPos + 1, DottedIP, ".", 1)
If i = 4 Then
pos = Len(DottedIP) + 1
End If

Display Advertisement by Country using ASP and COM Technology

noreply@blogger.com (Unknown) — Wed, 18 Nov 2009 10:29:00 +0000

Online advertisements these days are now raking in the big bucks due to the simple fact that it is now possible to display different advertisements to web visitors from different countries. By showing an advertisement that is relevant to the web visitor, there is a higher chance that it will attract the attention of the web visitor which tends to lead to a sale.

In this example, we use a fully functional IP2Location™ActiveX component available at http://www.ip2location.com/ip2location-country.zip to determine the visitor’s country by their IP address. Since the component is unregistered, there is a 5-second delay in every query.

To avoid any delays in the query, you can consider purchasing the IP2Location ActiveX/COM Component Version 3.0, which is a software development component and data solution for Windows®. You can tailor the content of your site dynamically based on visitor’s country, region, city, latitude, longitude, ZIP code, ISP, domain name, time zone, connection speed, IDD code, area code, weather station code and weather station name.

Copy the ActiveX component to the IIS web server. Then run the following command in DOS prompt.

C:\> regsvr32 ip2location.dll

Below is the sample code in ASP which will display advertisement by country.

<% ' Create server-side object Set ipObj = Server.CreateObject("IP2Location.Country") ' Initialize IP2Location object If ipObj.Initialize("demo") <> "OK" Then
response.write "IP2Location Initialization Failed."
End If

' Get visitor's IP address
IPaddr = Request.ServerVariables("REMOTE_ADDR")

' Detect visitor's country of origin by IP address
CountryName = ipObj.LookUpShortName(IPaddr)

' Free IP2Location object
Set ipObj = nothing

If CountryName = "JP" Then
' Visitor is from Japan
' Show advertisement from Japan
response.write "<img src=""Japan.jpg"" border=""0"" height=""200"" width=""100"">"
Else
' Visitor is not from Japan
' Show other advertisement
response.write "<img src=""US.jpg"" border=""0"" height=""200"" width=""100"">"
End If
%>

Displaying the Currency Type by Visitor's Country using PHP and MYSQL Database

noreply@blogger.com (Unknown) — Wed, 18 Nov 2009 06:48:00 +0000

More and more companies have started to take their businesses online which bring about significant cost reductions as opposed to traditional businesses. In addition, there is now an opportunity to take your products or services and market them to a larger audience of prospective customers from all over the world. To become a successful global player, online business owners need automatic IP-Country detection for localized currency type which will help them to boost their online sales by removing the foreign currency conversion barrier and converting their website visitors into buyers.

In this tutorial, we will use the IP2Location™IP-Country database to determine the country of origin for the web visitor just by checking the IP address. Instead of loading the full database with 50000+ records, we could simplify this tutorial with the assumption that only two different IP address ranges in the world. IP addresses of the range 0.0.0.0 - 126.255.255.255 originates from the United States. Meanwhile, IP addresses of the range 127.0.0.0 - 255.255.255.255 originates from Japan. Here we are creating a database called "IP2Location" with a table called "IPCountry" which contains our two IP address range records.

Step 1: Start the mysql command prompt. Run the 2 SQL command below to create the ‘IP2Location’ database and select it for use

mysql> CREATE DATABASE IP2Location ;
mysql> CONNECT IP2Location;

Step 2: Next, run the SQL statement below to create the ‘IPCountry’ table

mysql> CREATE TABLE IPCountry
--> (
--> ipFROM DOUBLE NOT NULL,
--> ipTO DOUBLE NOT NULL,
--> countrySHORT VARCHAR(2) NOT NULL,
--> countryLONG VARCHAR(100) NOT NULL,
--> PRIMARY KEY(ipFROM, ipTO)
--> );

Step 3: Run the SQL codes below to insert dummy data into the database

mysql> INSERT INTO IPCountry VALUES (0, 2130706431,'US','UNITED STATES');
mysql> INSERT INTO IPCountry VALUES (2130706432, 4294967295,'JP','JAPAN');

The full version of IP-Country database is available for subscription at $49/year from http://www.ip2location.com/ip-country.aspx.

If you have the full version of IP2Location™ IP-Country database, the import process is easier by using the LOAD DATA feature available in MYSQL.

PC:
mysql> LOAD DATA INFILE "/IPCountry.csv" INTO TABLE IPCountry FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\n';

Linux/Unix:
mysql> LOAD DATA INFILE "/IPCountry.csv" INTO TABLE IPCountry FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r\n';

Step 4: Run the SQL statement below to create the 'Countries' table

mysql> CREATE TABLE Countries
--> (
--> TLD VARCHAR(2) NOT NULL,
--> Country VARHCAR(100) NOT NULL,
--> FIPS104 VARCHAR(2) NOT NULL,
--> ISO2 VARCHAR(2) NOT NULL,
--> ISO3 VARCHAR(3) NOT NULL,
--> ISONo INT NOT NULL,
--> Capital VARCHAR(100) NOT NULL,
--> Region VARCHAR(100) NOT NULL,
--> Currency VARCHAR(50) NOT NULL,
--> CurrencyCode VARCHAR(3) NOT NULL,
--> Population DOUBLE NOT NULL,
--> );

The country information is available for FREE at http://www.ip2location.com/countryinformation.aspx . It consists of the top level domain (TLD), ISO-3166, country, capital, region, currency, currency code and population. Download and load the data into your database. It's available in several formats such as Comma-delimited ASCII, Microsoft® Access & Microsoft® Excel. The import process is same as the IP-Country database by using the LOAD DATA feature available in MYSQL.

You can use the SQL statement below to import the country information into the database.

mysql> LOAD DATA INFILE "/Countries.csv" INTO TABLE Countries FIELDS TERMINATED BY ',' ENCLOSED BY '"' LINES TERMINATED BY '\r';

Below is a sample code in PHP which will show you how to use the data to determine the correct currency to display the pricing.

<?php
// Replace this MYSQL server variables with actual configuration
$mysql_server = "mysql_server.com";
$mysql_user_name = "UserName";
$mysql_user_pass = "Password";

// Retrieve visitor IP address from server variable REMOTE_ADDR
$ipaddress = getenv(REMOTE_ADDR);

// Convert IP address to IP number for querying database
$ipno = Dot2LongIP($ipaddress);

// Connect to the database server
$link = mysql_connect($mysql_server, $mysql_user_name, $mysql_user_pass) or die("Could not connect to MySQL database");

// Connect to the IP2Location database

Show Visitor's Country Currency Using ASP and MS-SQL 2008 Database

noreply@blogger.com (Unknown) — Tue, 17 Nov 2009 05:46:00 +0000

More and more companies are realizing the importance of doing business online as a way of improving their market share. With this realization comes the need to deal with customers from around the world and their various currencies. This is when being able to show the pricing on a website in the visitor’s local currency would make the online shopping experience more user-friendly; eliminating the usual headache of foreign currency conversion.

In this tutorial, we will use the IP2Location™IP-Country database to determine the country of origin for the web visitor just by checking the IP address. Instead of loading the full database with 50000+ records, we could simplify this tutorial with the assumption that only two different IP address ranges in the world. IP addresses of the range 0.0.0.0 - 126.255.255.255 originates from the United States. Meanwhile, IP addresses of the range 127.0.0.0 - 255.255.255.255 originates from Japan. Here we are creating a database called "IP2Location" with a table called "IPCountry" which contains our two IP address range records.

Step 1: Start Microsoft SQL Server Management Studio.

Now, login to your database instance and then click on the New Query button. Copy the 2 lines of SQL codes below into the query window and press Execute to run the codes. This will create the ‘IP2Location’ database and select it for use.

CREATE DATABASE IP2Location

[ipFROM] [float] NOTNULL ,
[ipTO] [float] NOT NULL ,
[countrySHORT] [nvarchar] (2),
[countryLONG] [nvarchar] (64)
) ON [PRIMARY]
GO

Step 3: Run the SQL codes below to insert dummy data into the database.

INSERT INTO IPCountry VALUES (0, 2130706431,'US','UNITED STATES');
INSERT INTO IPCountry VALUES (2130706432, 4294967295,'JP','JAPAN');

The full version of IP-Country database is available for subscription at $49/year from http://www.ip2location.com/ip-country.aspx.

如何查询IP地址的地理位置?

noreply@blogger.com (Unknown) — Wed, 02 Sep 2009 10:20:00 +0000

此文章将指导你如何使用IP2Location Live Demo来确定IP地址的地理位置或归属地.

IP2Location是一种IP数据库工具让网站能够确定访客们的地理位置以及其他资料。IP2Location的IP 地址地理位置映射技术借助专有的 IP 地址查找数据库和技术，在不侵犯互联网用户隐私的前提下，可帮你确定访问者的具体地理位置。

IP是Internet Protocol的英文缩写意思, 是指“网络之间互连的协议” 。电脑在进行网络连接的时候是需要拥有一个IP地址。IP地址是用来标识互联网上计算机的逻辑地址。通过IP地址我们就能够将数据传送到特定的计算机中。每个IP地址都是独特和不会重复的，因此我们可以容易地获取信息从IP地址。

如果你想查询自己的IP地址的位置，你只需要进入www.ip2location.com ，你就可以在首页可以看到你的IP地址和地理信息，例如国家，区域，城市，纬度和经度，邮政编码，时区，网速，互联网服务提供商，网域，国家代码，地区代码和气象站。

上图的IP查詢工具显示网页访问者的IP地理位置信息如下：

IP地址: 219.137.144.53
地理位置 (国家，区域，城市): 中国, 广州, 广东
纬度/经度: 23.117纬度, 113.25经度
互联网服务提供商: 中国宽带互联网广东省网路
时区: UTC +08:00
网速: DSL
国家代码: 86
气象站: CHXX0037 -广州

如果你想探索其他IP地址的地理位置，你只需把IP地址输入在Live Product Demo的空栏里就可以获取IP地址的地理信息。

我们将示范如何用谷歌Google的IP地址(64.233.167.104)来查詢它的地理信息。我们把地址输入在Live Product Demo的空栏里，点击”Find Location” 的按钮。
