Argh, you sent shis message to me as private mail as well, and I answered
there.

Glue records are A records for the subdomain nameservers that are in the
*parent* zone.  They only exist when the domain is delegated to nameservers
that are in the domain they serve.  Since ninthave.net is delegated to
servers in the bytemark.co.uk domain, there are no glue records.

Telstra's DNS servers don't seem to be running BIND, so they may deal with
this anomaly differently than most other servers.

Maybe this is because Telstra hosts one of the authoritative servers for
the com.au domain.
