The "eq" does not work the same as regular expression pattern matching. The latter is much more powerful.
what would a wild card for :is not specific enough. The answer depends on what you want to match against.
For example, to match any digits (actually, between 1 and 3 digits) after the last ".", but require the initial 3 octets to be identical to what is specified, use:
My previous post shows a somewhat more flexible regular expression that allows but does not require leading zeros in an octet.
However, as afoken (++) pointed out, this may be too much flexibility if the value you are checking for comes from a "trusted" source, like the CGI module.
