Params::Validate::Checks::Net - Params::Validate checks for functions taking network-related arguments

  use Params::Validate::Checks qw<validate as>;
  use Params::Validate::Checks::Net;

  sub configure_website
  {
    my %arg = validate @_,
    {
      website => {as 'domain'},
      nameserver => {as 'domain'},
      ip_address => {as 'public_ip_address'},
    };

    # Do something with $arg{website}, $arg{nameserver}, $arg{ip_address} ...
  }

      device => {as 'hostname'},
      mac_address => {as 'mac_address'},

    };

    # Do something with $arg{device}, $arg{mac_address}, $arg{timeout} ...

This is a library of named checks for use with Params::Validate to validate function and method arguments that should be networky things: domain names, hostnames, IP addresses, or mac addresses. See Params::Validate::Checks for details of the overall system.

The following named checks are supplied by this module. In all cases only the syntax is checked, not that the entity in question actually exists on the network:

domain

an internet domain name, such as "123-reg.co.uk"; it must having a known top-level domain (such as ".uk")

hostname

an internet hostname; this includes all domain names but also unqualified hostnames like "www1", which may be valid on internal networks

ip_address

an IP address (version 4), such as "212.100.234.56"

public_ip_address

like ip_address, but excluding addresses such as "192.168.0.42" which are internal-only, not publicly reachable over the internet

mac_address

the mac address of a network device, such as "00:0E:35:17:F3:4E"

Feedback is welcome on further checks that should be added.

• Params::Validate::Checks, the framework this is using
• Data::Validate::Domain, provider of the domain name and hostname checks
• Data::Validate::IP, provider of the IP address checks
• Regexp::Common, provider of the mac address check
