🌸 NAME: Net::DHCP::Constants 🌸

Net::DHCP::Constants — constants for DHCP codes and options. That's the whole name-and-blurb situation, and honestly it's giving “useful little toolbox” energy.

✨ VERSION ✨

This page is at version 0.696. Periodt.

🦋 SYNOPSIS 🦋

use Net::DHCP::Constants;
print "DHCP option SUBNET_MASK is ", DHO_SUBNET_MASK();

No cap, that's all the synopsis.

💖 DESCRIPTION 💖

This page represents constants used in DHCP protocol, defined in RFC 1533, RFC 2132, RFC 2241, RFC 2485, RFC 2563, RFC 2937, RFC 3004, RFC 3011, RFC 3046.

🎀 TAGS 🎀

As mentioned above, constants can either be imported individually or in sets grouped by tag names. The tag names are:

  • bootp_codes — imports all of the basic BOOTP constants.
(01) BOOTREQUEST
(02) BOOTREPLY
  • htype_codes — imports all HTYPE (hardware address type) codes.
(01) HTYPE_ETHER
(06) HTYPE_IEEE802
(08) HTYPE_FDDI

Most common value is HTYPE_ETHER for “Ethernet”.

  • dhcp_message — imports all DHCP Message codes.

The (rfc2132) crew:

(01) DHCPDISCOVER
(02) DHCPOFFER
(03) DHCPREQUEST
(04) DHCPDECLINE
(05) DHCPACK
(06) DHCPNAK
(07) DHCPRELEASE
(08) DHCPINFORM
(09) DHCPFORCERENEW

And the (rfc4388) crew:

(10) DHCPLEASEQUERY
(11) DHCPLEASEUNASSIGNED
(12) DHCPLEASEUNKNOWN
(13) DHCPLEASEACTIVE
Nb. Previously Cisco used 13 for DHCPLEASEQUERY. If you need to decode or encode packets to communicate with such a system, you might simply use the integer rather than the constant — or use the updated constant and comment in your code appropriately.
  • dho_codes — imports all DHCP option codes.
