Net::DHCP::Constants(3)

NAME
Net::DHCP::Constants - Constants for DHCP codes and options

VERSION
version 0.7

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

DESCRIPTION
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

    Import all DHCP Message codes.

    (rfc2132)

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

    (rfc4388)

      (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

    Import all DHCP option codes.
