Don't put in an NS record in your domain that points to your server.  Or if
you already did, take it out.

It's just the zone file.

Also, when you register the domain with the parent domain registrar, don't
mention your server.  Just list the secondary nameservers that are
operating as secondaries (if the registration form specifically asks for
primary and secondary servers, put one of the ISP's servers as primary --
the distinction is really irrelevant to the registrar, so they shouldn't
even ask the questions this way, but many still do out of habit).
