Along with the development of IPv6 network, IPv6-based network is being applied
more and more widely. In IPv6 network, the 128-bit IPv6 addresses are usually
written in hexadecimal format. This feature has made manual address assignment
very difficult, as the format of IPv6 address doesn’t look intuitive. Therefore, the
automatic assignment of IPv6 addresses has become an important part of network
planning. In order to facilitate address assignment without manual intervention or with
minimum manual intervention, several methods and technologies have been
developed for address assignment and parameter configuration of IPv6 hosts. Here
are several methods for IPv6 address assignment:
1. Manual assignment
IPv6 address can be configured manually. This method is applicable to the
configuration of routing interface and static network parameters. Of course, manual
assignment may easily go wrong during the handling of hexadecimal 128-bit IPv6
addresses.
2. Stateless address auto-configuration
Stateless Address Auto-configuration is best suited for address assignment of IPv6
nodes without any manual intervention. To apply this method on an IPv6 node, this
node must be connected to at least one IPv6 router through the network. The IPv6
router will be configured by the administrator and send Router Advertisement
messages on the link. These messages will be received by local IPv6 nodes, which
will automatically complete the configuration of IPv6 address and routing parameters
without manual intervention.
3. Stateful DHCPv6
