Thanks Gerald, now that I'm looking in to it, it HAS started to bother me!
:)

There was a line in the hosts file indeed. However, when I remove the line,
and ping ns2.domain.com, it says it can't find the host?
Also, I noticed that in the resolv.conf file there is a line SEARCH
DOMAIN.COM and another line NAMESERVER xxx.xxx.xxx.xxx. However, DOMAIN.COM
actually is xxx.xxx.xxx.xxx. Would it be safe to remove that last line? I
mean, if it searches DOMAIN.COM and can't find an answer, it is no use
searching xxx.xxx.xxx.xxx either is it? Would it be better to add my
colocation host's nameserver there?
Do SEARCH and NAMESERVER mean the same (local/remote DNS lookups)? I read
some stuff about it, but I'm not sure I understand.

Thanks,

Martin
