Esmith::util::network

NAME

esmith::util::network - miscellaneous network utilities

SYNOPSIS

use esmith::util::network qw(the functions you want);

my $ip       = cleanIP($orig_ip); my $is_valid = isValidIP($ip); my $is_valid = isValidPort($port);

DESCRIPTION

This is a collection of generally useful functions for working with IP addresses.

Functions are exported only on request.

Functions

cleanIP

          my $ip = cleanIP($orig_ip);

If the $orig_ip is valid it will be cleaned up into a cannonical form, stripping any padding zeros and such.

isValidIP

          my $is_valid = isValidIP($ip);

Returns the IP given if $ip is a properly formatted IP address, undef otherwise.

isValidPort

          my $is_valid = isValidPort($port);

Returns true if $port is a properly formatted port, false otherwise.

cmpIP

Performs a cmp operation on two IP addresses.

isValidHostname

This function returns true if it is passed a valid RFC 921 hostname, false otherwise.

isValidEmail

This validation function validates an email address, using the Mail::RFC822::Address module. Additionally, by default, it permits a local address instead of a fully-qualified remote address, even checking the existence of said user in the accounts db.

If you don't wish to permit local addresses, pass the permitlocal option as false.

ie. esmith::util::isValidEmail($address, { permitlocal => 0 })
