Wildcard in NS record

First of all, I would add "thankfully" about the error message. BIND 9
is a lot more picky about the fact that zone files should follow the
standards - something that should have been enforced in the first
place, but for various reasons was not.

When you delegate, you need to set up a zone on the delegated-to
(RDATA part) server for the name in question. Since a host label can
be up to 63 characters long (IIRC), this means at least 36^63
combinations. That's a HUGE number. No one wants to set up that number
of zones. (My calculator gives me 1.11444*10^98 - that's roughly equal
to a single 1 followed by 98 zeroes. No, I'm not going to type them
all out.)

What are you trying to accomplish, anyway?
