Just now completed IPv6 certification with Hurricane Electric. It was very much fun! Starting was pretty much simple and basic, followed by email server running on v6 - which also I was doing already. I was stuck at most unexpected part - when I had to setup IPv6 based DNS servers. My first reaction was - that’s so simple….later on realized that system was just not accepting my entry and kept on giving error with AAAA records.

Hello everyone! Seems like Tata Communications routing table is changed (call it fixed) to route traffic for openDNS to Singapore. It’s not going to London anymore and I see very good latency from BSNL too (which uses Tata Comm for most of it’s International traffic). Here’s latest routing from BSNL to openDNS: HOST: laptop Loss% Snt Last Avg Best Wrst StDev 1. router2 0.0% 50 2.0 1.7 1.5 2.2 0.2 2.

Yesterday I had a very interesting discussion with our senior administrator. I was configuring reverse DNS records for our /24 block and I decided to use format - IP.static.domain.com thus if for IP 1.2.3.4, I pointed reverse DNS (PTR) to 1.2.3.4.static.domain.com When I got chance to show my work to my senior administrator, he said - It’s wrong to use 1.2.3.4.static.domain.com in a hostname. Too many dots will make DNS resolution very slow (forward - reverse - again forward).

And here we get latest EIG cable i.e Euro India Gateway cable in action. Although cable was up few months back, but it’s now we are getting some changes in routing table up. (Probably earlier was test mode?). Here’s a map of EIG cable. This was very interesting project because of few reasons - firstly it is one (of few) cable consortium’s where India’s biggest State owned telco BSNL (also known as NIB - National Internet Backbone).

And Ubuntu 11.04 released yesterday. I will do a seperate blog post reviewing Ubuntu 11.04 specially the new Unity interface, but for now I am trying to help Linux community by additonal mirror.
