Enable BIND cache server to resolve chinese domain name?

Hi,

Some of our customer complaint they could not visit
back to their web site, which use chinese domain name.
I google the net and found some one recommend to use
public-root.com servers in hint file.

I found domain name like xn--8pru44h.xn--55qx5d could
not be resolved either.

Our cache server runs BIND9.3.1 with root server list
from rs.internic.net.

Do I need to modify our cache server configuration to
enable it?

regards

Joe

Yes.

In order to get BIND to resolve a domain name under the "xn--55qx5d." TLD, you have to configure BIND's root hints to "point to" root servers making that delegation. If you do this you won't be able to simultaneously use the rs.internic.net listed servers.
