Page 1 of 2A mechanism by which a host informs a DHCPv6 infrastructure component about an IPv6 address it configured through another method, such as SLAAC. This can help DDI systems maintain address visibility and DNS registration.
Read definitionAn IPv6 prefix assigned to a requesting router for use on downstream links. The router can subnet the delegated prefix without receiving individual address leases for every downstream host.
Read definitionA DHCPv6 server function that selects and delegates IPv6 prefixes to requesting routers. It maintains prefix bindings and lifetimes in much the same way address leases are maintained.
Read definitionA DHCP Unique Identifier that identifies a DHCPv6 client or server across interfaces and restarts. Defined types include link-layer plus time, enterprise-based, link-layer only, and UUID-based DUIDs.
Read definitionIdentity Association, a DHCPv6 structure that groups one or more addresses or prefixes assigned to a client interface or purpose. Each IA is identified by an IAID and has associated timers and lifetimes.
Read definitionThe DHCPv6 option that carries an IPv6 address and its preferred and valid lifetimes within an identity association. It can also contain status or other address-specific suboptions.
Read definitionIdentity Association for Non-temporary Addresses. It is the standard DHCPv6 container used to request and assign ordinary stateful IPv6 addresses.
Read definitionIdentity Association for Prefix Delegation. It carries one or more delegated prefixes and related T1, T2, preferred, and valid lifetime information.
Read definitionIdentity Association for Temporary Addresses, an older DHCPv6 mechanism intended for temporary address assignment. RFC 9915 marks it obsolete.
Read definitionIdentity Association Identifier, a client-chosen value that distinguishes identity associations belonging to the same DUID. It is meaningful together with the client DUID and IA type.
Read definitionThe DHCPv6 option nested inside IA_PD that identifies a delegated IPv6 prefix and its preferred and valid lifetimes. It can also carry prefix-related status information.
Read definitionThe assignment of an IPv6 prefix to a requesting router through DHCPv6 so it can number downstream links. It is widely used for broadband, branch, home, mobile, and delegated tenant networks.
Read definitionA field in a Relay-forward message used to identify the client link to the DHCPv6 server. The server uses it to select appropriate address or prefix pools and options.
Read definitionAn ordinary stateful IPv6 address carried in an IA_NA, contrasted with the obsolete IA_TA temporary-address mechanism. The address still has preferred and valid lifetimes.
Read definitionA DHCPv6 option containing the option codes a client wants the server to return. It is analogous to the DHCPv4 Parameter Request List.
Read definitionAbbreviation for Option Request Option. A client lists desired configuration option codes in OPTION_ORO.
Read definitionCommon abbreviation for Prefix Delegation. DHCPv6 PD assigns a prefix to a requesting router rather than only assigning a single interface address.
Read definitionA field in a relay message identifying the client or previous relay from which the message was received. It helps preserve the relay chain and return path.
Read definitionA relative selection value whose interpretation depends on the protocol. MX and SRV use numeric preference or priority, while DHCPv6 servers can send an OPTION_PREFERENCE value to influence client selection.
Read definitionThe period during which an IPv6 address or prefix is preferred for new communication. After it expires but before valid lifetime ends, the resource is deprecated and should generally not be selected for new sessions.
Read definitionA DHCPv6 function that assigns prefixes to routers for downstream use. It separates routed-prefix allocation from individual host-address assignment.
Read definitionA server-initiated DHCPv6 message asking a client to initiate Renew or Information-request processing. Clients must indicate and follow the applicable reconfigure acceptance and authentication rules.
Read definitionA DHCPv6 message created by a relay agent to encapsulate a client message or another relay message on its way to a server. Multiple relays can create a relay chain.
Read definitionA DHCPv6 message sent from a server or upstream relay back through the relay chain toward the client. It contains the encapsulated response in the Relay Message option.
