WHAT IS IP ADDRESS OR INTERNET ADDRESS

2011-01-18T17:38:00.000-08:00

An internet is made up of a combination of physical networks (LANs or WANs) connected by ROUTERS. When a host communicates with another host, the packets may travel from one physical network to another using these routers. From this it is clear that communication at network layer also needs global identification system. A host must be identified uniquely and globally at this layer also. In addition, for efficient and optimum routing, each router must also be identified uniquely and globally at this layer.

The identifier that is used in the IP layer of the TCP/IP Protocol is called IP ADDRESS or INTERNET ADDRESS. It is a 32 bit binary address, implemented in software that uniquely and globally defines a host or a Router on the internet.

The IP address unique in sense that each address defines one, and only one,deice on the internet. Two devices on the internet can never have the same address. A device may have more than one Ip address if it is connected to more than physical network.

Each Ip address 32 bit binary digits ie; 4 blocks of 8bits(1 byte).
IP address has two parts:

NETWORK ID
HOST ID

Few bits of NETWORK ID determine the class of the address.

5 types Ip address classification

CLASS A : One (1)byte allotted to Network ID and remaining 3 for Host ID
CLASS B : First 2 byte for Network ID and remaining 2 byte for Host ID
CLASS C : First 3 byte for Network ID and remaining 1 byte for Host ID
CLASS D : No Network ID and Host ID. Known as Multicast Address
CLASS E : No Network ID and Host ID. Reserved for internet special use

PROXY SERVER- AN OVERVIEW

2011-01-17T17:56:00.000-08:00

In an enterprise that uses the Internet, a proxy server is a server that acts as an intermediary between a workstation user and the internet so that the enterprise can ensure security, administrative control, and caching service. A proxy server is associated with or part of gateway server that separates the enterprise network from the outside network and a firewall server that protects the enterprise network from outside intrusion.

A proxy server receives a request for an internet service from a user. If it passes filtering requirements, the proxy server, assuming it also a cache server, looks in its local cache of previously downloaded web pages. I f it finds the page, it returns it to the user without needing to forward the request to the internet. If the page is not in the cache,proxy server act as a client on behalf of user, uses one of its own IP addresses to request the page from server out on the internet. When the page is returned, the proxy server relates it to the original request and forward it on to the user. To the user, the Proxy server is invisible; all Internet requests and returned responses appear to be directly with the addressed Internet server.

This will help you to know some networking commands useful for troubleshooting the networks.

IPCONIG Or IPCONIG/ALL

IPCONFIG is a DOS utility, which can be used from MS-DOS to display the network settings currently assigned and given by network. This command can be utilized to verify a network connection as well as to verify your network settings.

NETSTAT

Display active TCP connections, ports on which the computer is listening, Ethernet statistics, the IP routing table,IPV4 statistics(for the IP,ICMP,TCP and UDP protocols), and IPv6 statistics(for the IPv6,ICMPv6, TCP over IPv6 and UDP over IPv6 protocols). Used without parameters, netstat displays active TCP connections.

TRACERT

The TRACERT command is used to visually see a network packet being sent and received and the amount of hops required for that packet to get its destination. Users with Microsoft Windows 2000 and windows Xp who need additional information network latency and network loss should also consider the PATHPING command.

PING

This command helps in determining TCP/IP Networks IP address as well as determine issues with the network and assists in resolving them.

PATHPING

It provides information about network loss at intermediate hops between a source and destination. Pathping sends multiple Echo Request messages to each router between a source and destination aver a period of time and then computer results based on packets returned from each router.

TELNET

TELNET is software that allows user to remotely access another computer such as server, network device, or other computer. With TELNET users can connect to a device or computer, manage a network device, setup a device, transfer files.
