    use Regexp::Common ();
    use Regexp::Common::net::CIDR ();

    while (<>) {
        /$RE{net}{CIDR}{IPv4}/ and print "Contains a CIDR.\n";
    }

DESCRIPTION

Patterns for CIDR blocks. Now only next IPv4 formats are supported:

  xxx.xxx/xx
  xxx.xxx.xxx/xx
  xxx.xxx.xxx.xxx/xx

With {-keep} stores address in $1 and number of bits in $2.

INSTALLATION

  perl Makefile.PL
  make
  make install

CAVEATS

As Regexp::Common doesn't work well with extensions named "Regexp::Common::xxx::yyy" you have to load this extension yourself with "use" or "require".
