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".
