----- Original Message -----
| 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

formatting for NS records is incorrect.  It should just read

                   NS ns1.exampleA.com
                   NS ns2.exampleA.com

where is your ns1.exampleA.com entry?
where is your ns2.exampleA.com entry?


| # 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

NS records are same as above.  Correct your formatting.

A records are not needed for NS records from a different zone, only for that zone

| How does that look?

Broken! :)
