Client Name resolutions

Dear friens,
I have installed and configured nethserver 6.6 as a primary DC. Then connected a Windows 7 client to it. the client name is Myclient and its ip is If i do nslookup from client it resolves and gogole’s ip address to name.
But I ping from client to its name, it looks like Pinging Myclient : : 1 :. No real IP shown in ping result.

What should i do to solve this problem.

That’s the IPv6 loopback address. If you’re pinging the client from itself, that’s normal operation.

You mean it is normal and i dont want panic
