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.
