NAME
    Regexp::Common::net::CIDR -- provide patterns for CDIR 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".
