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.
valid_domain($domain)Returns 1 if the given $domain string is defined
and is a domain that bind is capable of resolving,
otherwise returns 0.
valid_domain_rfc1035($domain)Returns 1 if the given $domain string is defined and is a valid
rfc1035 domain name, otherwise returns 0.
valid_ip($ip)Returns 1 if the given $ip string is defined and is an ip
address, otherwise returns 0.
The check for a valid ip address is currently very simple minded. It merely checks for a dotted-quad with all non-negative numbers with no number larger than 254.
valid_netmask($netmask)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.
