BT DNS not resolving certain addresses - e.g. www.aerobus.fr

[durks]

Using standard BT broadband at home, I am unable to resolve either of the domain names www.aerobus.fr or aerobus.fr - the DNS lookup just fails. But those are valid domain names and, if I try to resolve them via my mobile network provider, that works fine.

This implies a problem with BT's DNS servers.

Do other people here see the same failure?

The link work fine as does the domain name.

Okay, thanks. I will investigate further to see if I find some local issue. It's definitely odd though - all other domain name resolution is working fine for me.

I'm still puzzled by this - and I see the same problem on both Linux, and Windows.

Can you please tell me the IP addresses of the BT name servers you're using? Thanks.

For me, it's 81.139.56.100 (primary) and 81.139.57.100 (secondary).

They are the same as yours, 81.139.56.100 (primary) and 81.139.57.100 (secondary).
