NAME

       Regexp::Common::net::CIDR -- provide patterns for CIDR blocks.

SYNOPSIS

           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".
