It would require BIND 9 Info can be found at http://sysadmin.oreilly.com/news/views_0501.html quick sample: acl "local-addresses" { 10.0.0.0/8; 127.0.0.1/32; }; view "internal" { match-clients { local-addresses; }; recursion yes; zone "domain.tld" in { type master; file "domain.tld.internal"; }; }; view "external" { match-clients { 0/0; }; recursion no; zone "domain.tld" in { type master; file "domain.tld.external"; masters { 66.34.148.127; }; allow-transfer { secondary-nameservers; }; }; }; Robert On Friday 12 September 2003 10:11 pm, Ronnie Clark wrote: > Hello all, > > I have a questions that I just cannot get my brain > around.
