Net::IP::Match::Regexp allows you to check an IP address against one or
|
|
more IP ranges. It employs Perl's highly optimized regular expression
|
|
engine to do the hard work, so it is very fast. It is optimized for
|
|
speed by doing the match against a regexp which implicitly checks the
|
|
broadest IP ranges first. An advantage is that the regexp can be
|
|
computed and stored in advance (in source code, in a database table,
|
|
etc) and reused, saving much time if the IP ranges don't change too
|
|
often. The match can optionally report a value (e.g. a network name)
|
|
instead of just a boolean, which makes module useful for mapping IP
|
|
ranges to names or codes or anything else.
