Well, you probably don't want to resolve those names to 127.0.0.1, since
that will cause the client to connect to itself.
Generally speaking, you can accomplish what you want to do by defining a
root zone containing an A-record wildcard entry. Note that this is an
all-or-nothing commitment, though: you can't give a "default" answer for
names that don't exist (e.g. wwww.google.com) while at the same time
resolving names that do exist normally. A root-zone wildcard will
resolve *all* names to the address(es) you specify, and not even look at
any other sources of DNS information.
