For IP address lookups, use a net-* search; the base form always does a
hostname lookup, the net- prefix set are for IP lookups.
Specification,
10.12 Host list patterns for single-key lookups by host address
net-lsearch is the form which does exactly what you asked for, but look
at the details for net-iplsearch too, which is more useful in many
situations (lets you specify netblocks as well as single IP addresses).
Search the Spec for the string "net-" and you'll find quite a bit of
interesting stuff.
