airtel.in DNS broken

I wish I could say I don’t care about airtel.in, but because they are my ISP, I have to care :(.

The genius people at airtel.in CNAME-d the root record of their zone. 🙁

λ drill -t ns airtel.in @aaadel.mantraonline.com

Some less-strict resolvers seems to work with them, but others don’t. I mailed them (the WHOIS contact address) a month or two ago, but seems like it went to /dev/null. Today, when I went to access their looking glass, it again bit me. For now, I added lg.airtel.in to my hosts(5) file, where it will live, until it breaks.
