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

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.

  (08) DHCPINFORM
  (09) DHCPFORCERENEW
  (13) DHCPLEASEQUERY       # draft-ietf-dhc-leasequery-08.txt

dho_codes
