It depends on the registrars that the domains were registered through.
Some, like Network Solutions, have separate host and domain registrations,
and the hostname->IP association is in the host registration; changing that
one place updates the glue record for all of them.  Others have a single
registration for the domain and all its servers, so you'll need to update
each domain.

Depending on which kind of registrars were used, you may need that access
anyway.
