Thank you for all the help so far. To conclude: I have one physical server that answers to the following IP addresses: 1.1.1.1 1.1.1.2 1.1.1.3 1.1.1.4 I need 1.1.1.1 & 1.1.1.2 to be the name servers for exampleA.com, and 1.1.1.3 & 1.1.1.4 to be the nameservers for exampleB.com. I have these files: # cat /etc/named.conf options { directory "/etc"; pid-file "/var/run/named/named.pid"; listen-on { any; }; }; zone "." { type hint; file "/etc/db.cache"; }; zone "exampleA.com" { type master; file "/var/named/exampleA.com.hosts"; }; zone "exampleB.com" { type master; file "/var/named/exampleB.com.hosts"; }; # cat /var/named/exampleA.com.hosts $ORIGIN exampleA.com. $TTL 1h exampleA.com. IN SOA ns1.exampleA.com. ns2.exampleA.com. ( 1; Serial - increment me 10800 3600 604800 38400 ) exampleA.com. IN NS ns1.exampleA.com. exampleA.com. IN NS ns2.exampleA.com. exampleA.com. IN A 1.1.1.1 exampleA.com. IN A 1.1.1.2 # cat /var/named/exampleB.com.hosts $ORIGIN exampleB.com. $TTL 1h exampleB.com. IN SOA ns1.exampleB.com. ns2.exampleB.com. ( 1; Serial - increment me 10800 3600 604800 38400 ) exampleB.com. IN NS ns1.exampleB.com. exampleB.com. IN NS ns2.exampleB.com. exampleB.com. IN A 1.1.1.3 exampleB.com. IN A 1.1.1.4 How does that look? -- Dotan Cohen http://gibberish.co.il http://what-is-what.com _______________________________________________ CentOS mailing list CentOS@xxxxxxxxxx http://lists.centos.org/mailman/listinfo/centos
