IPv6 Autoconfig
The IPv6 address composes of two parts, the prefix and the interface ID.
There are two ways to dynamically configure IPv6 address on hosts. One is “stateful” configuration,
for example using DHCPv6 (which resembles its counterpart DHCP in IPv4.) In the stateful auto-
configuration model, hosts obtain interface addresses and/or configuration information and
parameters from a DHCPv6 server. The Server maintains a database that keeps track of which
addresses have been assigned to which hosts.
The second way is “stateless” configuration. Stateless auto-configuration requires no manual
configuration of hosts, minimal (if any) configuration of routers, and no additional servers. The
stateless mechanism allows a host to generate its own addresses using a combination of locally
available information (MAC address) and information (prefix) advertised by routers. Routers
advertise prefixes that identify the subnet(s) associated with a link, while hosts generate an
"interface identifier" that uniquely identifies an interface on a subnet. An address is formed by
combining the two. When using stateless configuration, you needn’t configure anything on the client.
