How to Delegate ?

[Kevin Darcy]

You can only delegate from a parent to a child zone. To delegate
ccc.bbb.aaa.in-addr.arpa, for instance, i.e. the child zone, you'd need to be
master for bbb.aaa.in-addr.arpa, i.e. its parent. You'd just add NS records to
the parent zone file, e.g.

ccc    in    ns    {nameserver}

If you're not master for the parent zone, then whoever is, would need to make
the delegation.
