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".
