IPv6 Address Assignment Method
Supported IPv6 address assignment methods:
•
Manual Assignment: An IPv6 address and other configuration parameters (e.g.,
DNS server) for the phone can be statically configured by an administrator.
•
Stateless Address Autoconfiguration (SLAAC)/ICMPv6: SLAAC is one of the
most convenient methods to assign IP addresses to IPv6 nodes. SLAAC requires
no manual configuration of the phone, minimal (if any) configuration of routers,
and no additional servers. To use IPv6 SLAAC, the phone must be connected to a
network with at least one IPv6 router connected. This router is configured by the
network administrator and sends out Router Advertisement announcements
onto the link. These announcements can allow the on-link connected phone to
configure itself with IPv6 address, as specified in RFC 4862.
•
Stateful DHCPv6: The Dynamic Host Configuration Protocol for IPv6 (DHCPv6)
has been standardized by the IETF through RFC 3315. DHCPv6 enables DHCP
servers to pass configuration parameters such as IPv6 network addresses to IPv6
nodes. It offers the capability of automatic allocation of reusable network
addresses and additional configuration flexibility. This protocol is a stateful
counterpart to “IPv6 Stateless Address Autoconfiguration” (
), and can
be used separately or concurrently with the latter to obtain configuration
parameters.
IPv6 Address and Network Setting Resources
The following table lists where the phone obtains the IPv6 address and other network
settings:
DHCPv6
SLAAC
(ICMPv6)
How the phone obtains the IPv6 address and network settings?
Disabled
Disabled
The static IPv6 address and other network settings must be manually
configured.
Enabled
Disabled
The phone can obtain the IPv6 address and other network settings via
DHCPv6.
Enabled
Enabled
If the SLAAC server is working, the server can specify the phone to obtain the
IPv6 address and other network settings either from DHCPv6 or SLAAC.
If the SLAAC server is not working, the phone will try to obtain the IPv6
address and other network settings via DHCPv6.
