Glossary:

DHCP domain.
(RFC 3315) A set of links managed by DHCP and operated by a single administrative entity.

DHCP realm.
(RFC 3315) A name used to identify the DHCP administrative domain from which a DHCP authentication key was selected.

DHCP relay agent.
(RFC 3315) A node that acts as an intermediary to deliver DHCP messages between clients and servers, and is on the same link as the client.

DUID, DHCP Unique IDentifier.
(RFC 3315) Each DHCP client and server has a DUID. DHCP servers use DUIDs to identify clients for the selection of configuration parameters and in the association of IAs with clients. DHCP clients use DUIDs to identify a server in messages where a server needs to be identified.

IA, Identity association.
A collection of addresses assigned to a client. Each IA has an associated IAID. A client may have more than one IA assigned to it. Each IA holds one type of address.

IAID, Identity association identifier.
(RFC 3315) An identifier for an IA, chosen by the client. Each IA has an IAID, which is chosen to be unique among all IAIDs for IAs belonging to that client.
