If it doesn't resolve to 127.0.0.1 it isn't working.

Code:
rcgreen@blue:~$ nslookup 00info.com

The reason it isn't resolving is because the host is down, not because
of your black hole dns. The request is being forwarded to your ISP,
and then failing to resolve. Probably something wrong with the syntax
of your zone file.
