Thank you. That is quite what I had suspected, and of course the zone
files that I am experimenting with reflect that. How is this:


# 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 )
             IN      NS      ns1.exampleA.com.
             IN      NS      ns2.exampleA.com.
exampleA.com. IN      A       1.1.1.1
exampleA.com. IN      A       1.1.1.2
ns1           IN  A   1.1.1.1
ns2           IN  A   1.1.1.2
