can ping to unresolve domains

[sjaak]

Hello

I have a strainge problem.
If i ping from the server to lets say yahooxx.com I get response !!!

ping yahooxx.com

result is :
PING yahooxx.com.mydomain.com (xxx.xxx.xxx.xxx) 56(84) bytes of data.
64 bytes from MyIP: icmp_seq=1 ttl=64 time=0.021 ms
64 bytes from MyIP: icmp_seq=2 ttl=64 time=0.037 ms
64 bytes from MyIP: icmp_seq=3 ttl=64 time=0.022 ms
64 bytes from MyIP: icmp_seq=4 ttl=64 time=0.020 ms

What's wrong domain yahooxx.com doesn't excist.
And this is strainge yahooxx.com.mydomain.com
What could be wrong ?

Does your nameserver have wildcard DNS set up for your domain?

And if so, is your nameserver listed in /etc/resolv.conf ?
