for bind vic^H^H^Husers

    dig +norec zone.name. @delegatee.name. soa

to check the ns rrset at the [proposed] delegatee

    dig +norec zone.name. @delegatee.name. ns

on later digs, you can also use the +short option if you don't want
to see too much detail.

serious pedants can also check for response via tcp, as opposed to
just the default udp.

could you amplify?

or if a proper subset of the delegations are lame.

or if the ns rrset at a delegatee does not match that which
was specified to be installed in the delegating zone file.
