Net::Bind::Utils - various routines common across Net::Bind packages.

  use Net::Bind::Utils qw(valid_domain valid_ip);

A catch-all place for various routines that are useful across most, if not all, of the Net::Bind interfaces.

This module is not designed to be subclassable.

Returns 1 if the given $domain string is defined and is a domain that bind is capable of resolving, otherwise returns 0.

Returns 1 if the given $domain string is defined and is a valid rfc1035 domain name, otherwise returns 0.

Returns 1 if the given $ip string is defined and is an ip address, otherwise returns 0.

The check for a valid ip address is currently very simple minded. It merely checks for a dotted-quad with all non-negative numbers with no number larger than 254.

Returns 1 if the given $netmask string is defined and is a netmask, otherwise return 0.

The check for a valid netmask is currently very simple minded. It merely checks for a dotted-quad with all non-negative numbers with no number larger than 255.
