I take it that it's in Firefox you see this behaviour, please let us know if that's not the case. Both bind9-host and nslookup can handle this domain name, but not Firefox.

I do not agree, this is not a firefox bug (the kink works for me using Intrepid and firefox 3.0.6 or 3.0.7), i don't understand the bug because i cannot reproduce it, can you be more specific about the versions of Ubuntu and firefox you are using ?

which packets are you using ?

please provide the output of the following commands :

lsb_release -a
firefox -v
dpkg -l firefox

This is on amd64 if that matters.

is this happening only with firefox ? or even when you do nslookup or dig or browse via Opera / Konqueror or other ?

I am able to confirm this on Jaunty firefox version 3.1 I will test with 3.0 and 3.2 in a few minutes.

dig only apply to domain name, not to URL.

just do "dig domain" without http:// and /

I don't think it's a firefox bug,because opera,konqueror and curl doesn't work,other linux system like arch puppy have the same problem.
my system: Ubuntu 8.10
firefox version: 3.0.6

You might be right actually. The command "getent hosts blurr-.javaeye.com" returns nothing. Does this make it a glibc bug?

This might be a duplicate of bug 144431 in glibc
