IPv6 NAT from a webhosting perspective

By | Technical | No Comments

IPv6 is something that’s been coming for a long time now, to address the shortage of IPv4 addresses. If you’re not familiar with the problem, it goes like this: Networked devices need addresses to find and talk to each other. When the internet was invented there was capacity to address up to 4 billion devices. We’re now running out of addresses for all the networked devices in the world. There are two established technological ways out of this problem: Be frugal and share addresses, this is called NAT Move to a system with capacity for many more addresses, this new system is called IPv6. It’s not compatible with the old IPv4 system, but it gives us about 50 octillion addresses for every person on the planet NAT is a really…

Dual-stack IPv6/IPv4 as standard on new US deployments

By | Technical | No Comments

The focus for this post is obviously about our IPv6 deployment plans, but I’d like to take a small detour through our US presence on the way there. Anchor’s networking and automation gurus have been hard at work preparing our new kit over in the US, and the day we go live is fast approaching. In the process we’ve had literally zero personal presence over there, not one plane ticket was bought. That we can get away with this is mostly thanks to two things: Equinix and DRACs (Dell’s remote-management interface). Equinix One of the reasons we went with Equinix is their high level of support, which goes nicely with Anchor’s approach to business. The servers were dropshipped direct to the LA3 datacentre where staff unpacked them and racked them…

Keeping your finger on the pulse of your network

By | Technical | No Comments

In the past I’ve written about a few ways you can set up decent IP traffic accounting on your network. If you have already set this up and are champing at the bit for more ways your can increase situational awareness of your network state you can try one of the following tools related to pmacct: http://www.pmacct.net/pnrg/ http://www.aptivate.org/Projects.BMOTools.pmGraph.html http://www.net-track.ch/opensource/pmacct-snmp/ http://code.google.com/p/netact/ http://projects.celuloza.ro/bwstat/ http://www.pmacct.net/fe/ http://sven.anderson.de/flox/ http://www.ntop.org/ http://bandwidthd.sourceforge.net/ http://nfsen.sourceforge.net/ http://etherape.sourceforge.net/ These tools allows you to graph and/or analyse your traffic data in a variety of ways. If you are currently using one or more of these, drop us a comment and let us know your success or failure stories!

New IPv6 allocation for Anchor

By | Technical | No Comments

As mentioned on this blog a few times before, we’re committed to getting IPv6 happening at Anchor. While the live rollout date is probably still a while away, we have at least begun making some inroads on the progress. Today we received our IPv6 allocation from APNIC: 2407:7800::/32 That equates to about 2^96 IP addresses, roughly 10^28 or 79228162514264337593543950336. Quite a mind-boggling number. We’ll continue our research, documentation, testing and will let you know when we are ready to start handing out live addresses. Until then, if you are a customer or would like to be, please let us know you are interested in IPv6, as there are still not too many hosting companies who are using it. Amazing, given IPv4 addresses will run out in a couple of years…

New IPv4 allocation for Anchor

By | Technical | One Comment

Nobody is under any pretences that IPv6 will be close to 100% usage globally any time soon, so despite many entities having firm IPv6 plans or infrastructure already in place, demand for IPv4 is still strong. With that in mind, we’ve just acquired a new allocation from APNIC which will hopefully see us through until IPv6 is dominant on the Internet. 110.173.128.0/19 This allocation is from the 110/8 class A that was allocated to APNIC in November 2008, and represents a tripling of Anchor’s current IPv4 space. We’ll be following our current strict allocation policies to ensure it is the last additional IPv4 allocation we will need, and continuing with our current IPv6 plans as all responsible entities on the Internet should be doing.

IPv6 Implementors Conference

By | Company News, Technical | No Comments

I was dropped a quick note by one of the speakers at the IPv6 Implementors Conference which is being hosted by Google – http://sites.google.com/site/ipv6implementors/conference2009/ Sadly I had no idea this conference was on, as it looks like a valuable opportunity to learn about IPv6 and the progress it is making in the wild. I did get a couple of handy tips about how to improve our implementation plan though so not all was lost. If you are attending this conference, you are more than welcome to leave comments on this blog post with your learnings – or even link to your own site – the more the merrier.

The Future Of The Internet

By | Technical | One Comment

On day two of Linux Conf I was able to attend two presentations on IPv6 – System Administration Consequences of the Endgame of IPv4 and the Deployment of IPv6 by AARNET’s Glen Turner and Google and IPv6 by Angus Lees. Both were extremely informative and made it clear to me that we need to start gearing up for IPv6. By “we”, I mean the world. Don’t get me wrong – if you are the average home user IPv6 (or even IPv4) will mean nothing to you and the advent of IPv6 addressing en masse will likely pass you by without you even noticing. Much like the Y2K bug though, it will only be with the coordinated efforts of the best network and systems administrators around the world that we’ll be…
