A URL containing an IP address is not canonical for HTTP. HTTP 1.1 does
virtual hosting via the "Host:" header, so multiple distinct servers can be
on a single IP. If you restrict based on IP, you'll block access to both
http://www.juicysex.com/ and http://www.bible-history.org/, should they both
be on the same box.
