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!

Testing your connectivity

Recently I blogged about our new IPv4 address allocation. While we don’t need to start using it for a while as we have been conserving IP addresses quite well, and gave ourselves plenty of time before we actually need to use the new allocation, it is a good idea to check that it is accessible to the Internet at large. Our new allocation is from the block 110.0.0.0/8 which was only allocated to the Asia-Pacific regional registry APNIC last November. Prior to it being allocated to APNIC, it would have been in a state affectionately known as “bogon” to network administrators. Bogons are network ranges that aren’t in use, and therefore can be safely ignored by all live networks on the Internet. There have been cases where spammers or other…

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.

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…
