forward zone

Tue Feb 11 14:46:47 UTC 2003

Ya, now it work but if I don't resolve as first (from a client) the name of
ns1.child.mydomain.it    I'm unable to resolve any other IP/name in the
child.mydomain.it zone.
If in the NSLOOKUP try to resolve ns1.child.mydomain.it and after
anotherhost.child.mydomain.it      it work fine.

Do you know why?.

           In the parent zone add NS records for the child zone.

           e.g.
           child.mydomain.it. NS <nameserver1>
           child.mydomain.it. NS <nameserver2>

           If nameserver1 and/or nameserver2 are below mydomain.it add
           glue A/AAAA records for the them to the parent zone as well.

           e.g.

           child.mydomain.it. NS ns1.child.mydomain.it.
           child.mydomain.it. NS ns1.example.net.
           ns1.child.mydomain.it. A 1.2.3.4

           Note there is no glue records for ns1.example.net as it is
           *not* below mydomain.it.

           Note the child zone also needs to have the A record for
           ns1.child.mydomain.it.  Glue records are *copies* of records
           from child zones which are used to avoid the catch 22 situation
           of requiring the address to get the address.  If you fail to
           have the original records in the child zone you will cause
           intermittent failures for lookups in the child zone.
