Using an IPv6 Tunnel Broker With Linux

Matt Ryanczak — Mon, 11 Jul 2011 16:14:02 +0000

In previous articles I’ve covered the basics of configuring IPv6 on your Linux host. Knowing how to enable and configure IPv6 is valuable but this knowledge is not very useful if you can’t use it to connect to anything. At present most people are not connected to the IPv6 Internet because their ISP lacks support [...]

Interview on Junos Connect

Chris Grundemann — Wed, 01 Jun 2011 15:44:16 +0000

I was recently flown out to Juniper HQ in Sunnyvale to record an on-camera interview about my two IPv6 Day One books for an episode of Junos Connect. Although the interview was completed in about 15 minutes after just 3 takes (two to be sure we had it, one due to someone walking through the [...]

Talking to Juniper about IPv6 and Day One

Chris Grundemann — Tue, 31 May 2011 16:10:28 +0000

I was recently in Sunnyvale at Juniper HQ to record an interview for an IPv6 focused episode of Junos Connect (more on that laterhere). While there, Dan Backman and I recorded a couple of podcasts for distribution within Juniper. They’re not too overly boring so I figured I’d post them up here in case folks [...]

Rocky Mountain IPv6 Summit Presentations Now Available

Scott Hogg — Thu, 26 May 2011 14:23:45 +0000

The 2011 Rocky Mountain IPv6 Summit attracted nearly 400 attendees this year. The increase in interest in IPv6 can be attributed to the recent news about IPv4 address depletion. The other factor driving attendance at the event was the lack of IPv6 training resources available. The event included a pre-conference tutorial, a 2-day general session [...]

IPv6: Configuring Debian and Using Sysctl

Matt Ryanczak — Mon, 16 May 2011 09:01:50 +0000

In a previous article I discussed configuring IPv6 on a Redhat based Linux distribution. That article covered CentOS, Oracle and other Linux distributions based on Red Hat Enterprise Linux (RHEL). There is, however, another Linux distribution that is as widely used as Red Hat and has spawned at least as many derivatives and that is [...]

Transition Techniques for IPv6 – Some Techniques are ‘Bad’!

Mukom Akong Tamon — Mon, 02 May 2011 15:08:35 +0000

Transition techniques are a key set of tools that will help organizations as they plan and deploy their transition to IPv6. However, not all transition techniques are born equal. This post makes the case for the fact that some types of transition techniques should not be emphasized (and should in fact be discouraged) when teaching IPv6, as they might hurt IPv6 deployment.

IPv6 Routing Deep Dive

Chris — Fri, 29 Apr 2011 16:13:02 +0000

The 2011 Rocky Mountain IPv6 Summit was held in Denver earlier this week (25-27 April) at the Grand Hyatt. It was a great event, as we have come to expect from the Rocky Mountain IPv6 Task Force. I was especially pleased that they stepped the presentation content up a notch with regard to technical depth [...]

Day One: Advanced IPv6 Configuration

Chris — Wed, 27 Apr 2011 23:11:58 +0000

Day One: Advanced IPv6 Configuration is a sequel to my first book, Day One: Exploring IPv6, and picks up right where it left off. Namely with BGP. In addition to a fairly thorough look at BGP (iBGP and eBGP / native IPv6 peering and sharing IPv6 routes over IPv4 peering), the book jumps into a few of the additional and often overlooked aspects of deploying an IPv6 network. This includes a look into topics and tools including VRRP, ICMPv6 rate limiting, CoS, IPv6 path MTU discovery, DHCPv6, zero hop-limit, Multicast Listener Discovery (MLD) and Duplicate Address Detection (DAD).

Will your IPv6 site appear in search engines?

Franck Martin — Thu, 31 Mar 2011 23:37:09 +0000

This seems another hindrance for the adoption of IPv6 on websites. Search engines use crawlers to go around all pages on all websites on the Internet (except when they are told not to by the robots.txt file on each site). From this crawling they index pages and websites so that the search engine can find [...]

ICANN Community Briefing on IPv6

Chris Grundemann — Fri, 04 Mar 2011 19:19:54 +0000

I just sat in on a call/talk/presentation by Leo Vegoda (the guy who operates the IANA for ICANN) on IPv6. Overall, it was a great primer on IPv6, the exhaustion of IPv4 and the future of Internet addressing. One idea that I would especially like to echo here is his suggestion for everyone to send [...]

Managing Customer Perceptions — Fix the problem, not the blame

Owen DeLong — Tue, 01 Mar 2011 20:01:33 +0000

Most of this article is not directly related to IPv6, however, the issue it addresses will, in my opinion, be a key issue for organizations to consider as they manage the transition towards IPv6. I spend a lot of time working with various organizations and one thing that has stood out to me over the [...]

Cooperation remains the Key to the future of Internetworking

Owen DeLong — Tue, 22 Feb 2011 18:17:07 +0000

This article will seek to dispell some common myths as well as enlighten, entertain, and hopefully educate the audience on key principles underpinning what we call “The Internet”. So that I can speak candidly here, I have to include the following disclaimer: The opinions in this piece are mine and mine alone. I am not [...]

NAT444 (CGN/LSN) and What it Breaks

Chris Grundemann — Mon, 14 Feb 2011 16:30:47 +0000

Before we look at what breaks, I should probably make sure that you know what it is that I’m talking about here. If you already know all about traditional NAT and address overloading, skip to the NAT444 section. If you are familiar with that as well, feel free to skip right to the list of [...]

Enterprise Multihoming in IPv6

Owen DeLong — Wed, 09 Feb 2011 16:48:00 +0000

Enterprises can easily multihome in IPv6 even without NAT. Read the full article for information and analysis on how.

And then there were none.

Chris Grundemann — Thu, 03 Feb 2011 14:50:01 +0000

APNIC has requested and received two IPv4 /8s (39/8 & 106/8), which has in turn triggered the “last five” policy at IANA giving each Regional Internet Registry (RIR) one additional /8 and depleting the global free pool of IPv4 forever. The final five went out like this just moments ago: 102/8 AfriNIC 2011-02 [...]

The Last Five IPv4 “Slash Eights” (/8s)

Chris Grundemann — Tue, 01 Feb 2011 01:11:51 +0000

Not overly surprisingly, APNIC officially received two more IPv4 /8 (“slash eights”) from the IANA today: Hi, The IANA IPv4 registry has been updated to reflect the allocation of two IPv4 /8 blocks to APNIC in January 2011: 39/8 and 106/8. 39/8 APNIC 2011-01 whois.apnic.net ALLOCATED 106/8 APNIC 2011-01 whois.apnic.net ALLOCATED [...]

IPv6, A Numbers Game

Chris Grundemann — Wed, 26 Jan 2011 17:58:56 +0000

I was planning on writing this great breakthrough piece on IPv6 subnet sizes, like how many /48s are in a /32 or how many /56s are in a /24, etc… But then I stumbled across a great PDF from ARIN and realized that all the work was already done. So I ended up not posting [...]

Configuring IPv6 on Redhat (CentOS) Linux

Matt Ryanczak — Thu, 20 Jan 2011 20:39:32 +0000

Linux has supported IPv6 since the 2.2 series of kernels. Back in the late 90s and early 2000s there were actually two different implementations of IPv6 in Linux. One implementation was part of the mainline kernel at the time but was not feature complete. Another implementation was produced by the USAGI/WIDE Project, which was formed [...]

The road to IPv6 goes also via 6to4

Franck Martin — Fri, 14 Jan 2011 00:08:17 +0000

One of the transition mechanisms for IPv6 is 6to4. This is an automatic mechanism which encapsulates IPv6 packets inside IPv4 packets. The packets are sent to relays which are located around the world. A list of these public relays are available at: http://www.bgpmon.net/6to4.php?week=4 How do these relays work? They use the same technology as the [...]

IPv4 – Is the sky falling?

Chris Grundemann — Wed, 12 Jan 2011 03:08:22 +0000

There are folks who have, in the past, cried wolf with regard to IPv4 free pool depletion and the need for IPv6 adoption. Different people had different reasons for doing so and some were likely ulterior. Since then, all of the reputable folks focusing on IPv6 deployment have removed these alarmists and distanced themselves from [...]

iPhone IPv6 Debugging Simplified with Ip6config

James Hamilton — Sun, 09 Jan 2011 17:55:49 +0000

With Apple’s release of iOS 4.0 in June 2010, IPv6 came to the iPhone® in full force, if very quietly. So quietly, in fact, some commentators believed that IPv6 support that was present in the 4.0 beta had been removed from the public iOS 4.0 release. Why the confusion over support for the Internet’s next-generation [...]

Can we do everything with IPv6 that we do with IPv4?

Franck Martin — Mon, 03 Jan 2011 20:10:49 +0000

While the deployment of IPv6 is relatively easy, it is still limited in the enterprise to the capability of the hardware. For instance lot of enterprises need systems with redundancy and failover mode. For instance Cisco ASA provides a firewall solution with hot standby capability. You place two boxes next to each other and the [...]

SMTP and IPv6: How to with Zimbra (and postfix)

Franck Martin — Wed, 29 Dec 2010 20:08:03 +0000

This post was posted in July on our blog. This week we migrated our Zimbra mailsever to send and receive email over IPv6. While Zimbra does not officialy supports IPv6, the underlying component to send and receive email, postfix, supports IPv6 for a long time. The process is therefore to modify the postfix config to [...]

Petitioning ARIN-prop-125

Chris Grundemann — Thu, 23 Dec 2010 01:00:43 +0000

Here we go again! As what might be my last act as a “regular” member of the ARIN community, I have decided to launch a discussion petition of ARIN-prop-125, Efficient Utilization of IPv4 Requires Dual-Stack. I describe the need and purpose for this proposal in the rational: In this period of available IPv4 address scarcity [...]
