Airtel hijacking NXDOMAIN queries

Anurag Bhatia
Back in India after amazing APRICOT 2013 at Singapore. It was nice to stay in East Asia for a while and look around. :) Anyways, issue for today - I have been using Airtel DNS servers from quite sometime since BSNL has crappy DNS while Google gives issues with Akamai while OpenDNS doesn’t has any node in India yet. Today I noticed a NXDOMAIN redirection for a non-working domain and later investigated.
