DHCPv6 & IPv6 Address Assignment

Medium

Free preview · 2 of 5 steps

IPv6 has two address assignment methods

In IPv4, DHCP is the only dynamic address assignment method. IPv6 adds SLAAC (Stateless Address Autoconfiguration) — hosts can configure themselves without any server by combining the network prefix from router advertisements with a locally-generated interface identifier.

DHCPv6 provides the IPv6 equivalent of DHCPv4: server-controlled, tracked, auditable address assignment. Router Advertisements control which method hosts use.
