Working with named services can be a pain when you want to go back and forth between the port and its real name. This module helps alleviate some of those pain points by defining some helping hashes, functions, and regular expressions.
Regular expression to match any port, irregardless of which protocol it goes over.
While this is a highly optimized regex, you should consider using the hashes or subroutines instead as they are much better. This is merely for your convenience.
Case is ignored and the protocol must match on a word boundary!
# Matches
$port =~ $IANA_REGEX_PORTS;
# Won't match
$non_port =~ $IANA_REGEX_PORTS;

Helper function to check if the given port (and optional protocol) is defined by IANA.
If only the port is given, then it will be checked across all protocols while restricting the search to just the provided protocol if one is given.
Port (int)StringBoolean iana_has_port( 22 ); # 1
iana_has_port( 34221 ); # 0
iana_has_port( 271, 'tcp' ); # 1
iana_has_port( 271, 'udp' ); # 0
Helper function to check if the given service (and optional protocol) is defined by IANA.
If only the service name is given, then it will be checked across all protocols while restricting the search to just the provided protocol if one is given.
StringStringBoolean iana_has_service( 'ssh' ); # 1
iana_has_service( 'not-ss' ); # 0
iana_has_service( 'xmpp-server', 'tcp' ); # 1
iana_has_service( 'xmpp-server', 'udp' ); # 0
Helper function to get the known services for the given port and optional protocol, as defined by IANA.
If only the port is given, then you will get back an array ref containing all of the services that are defined by IANA. If a protocol is specified, then the returned prtocols will be limited to those running over that type.
Port (int)StringArray iana_info_for_port( 22 ); # [qw/ ssh /]
iana_info_for_port( 34221 ); # undef
iana_info_for_port( 271, 'tcp' ); # [qw/ pt-tls /]
iana_info_for_port( 271, 'udp' ); # undef
Helper function to get the known information for the given service and optional protocol, as defined by IANA.
If only the service is given, then you will get back a hash ref containing the normal return information hash for each defined protocol for that service.
StringStringHashThe returned hash contains the following pieces of information (keys are lower case):
iana_info_for_service( 'xribs' ); # { udp => { 2025 => { desc => '', name => 'xribs', note => '' } } }
iana_info_for_service( 'not-ss' ); # undef
iana_info_for_service( 'xribs', 'tcp' ); # undef
iana_info_for_service( 'xribs', 'udp' ); # { 2025 => { desc => '', name => 'xribs', note => '' } }
