dude. each and every one of the airtel user (except for us few) is accessing those IPs. just stop using them and use the third party ones. and stay cool. they won't harm your browsing experience a bit.i stopped using airtel IPs around 1.5 years back. never got back to them.
yes, most ISPs do a shoddy job providing DNS services. So, we're left at the mercy of Open DNS or the likes. They do quite a decent job but they take a bit to respond as they're geographically away from us.
