dns: bind9: cascading server sub-zone

polemon · 11-18-2009, 07:45 AM

Hello,

I'm running a DNS server for a sub-domain. This DNS server is supposed to ask one specific other DNS server for lookups outside its sub-domain, and not the root servers.

How do I do that?

I'm using bind9 as named server.

Cheers,

add following lines within OPTION part in named.conf file

forwarders { x.x.x.x; };

x.x.x.x dns server address outside your subdomain

for more info check FORWARDER section in following link
