IPv6 is the next generation network layer protocol, designed as a replacement for the

current IPv4 protocol. IPv6 is developed by the Internet Engineering Task Force (IETF) to

deal with the long-anticipated problem of IPv4 address exhaustion. IPv6 uses a 128-bit

address, consisting of eight groups of four hexadecimal digits separated by colons. VoIP

network based on IPv6 can ensure QoS, a set of service requirements to deliver

performance guarantee while transporting traffic over the network.

IPv6 Address Assignment Method

Supported IPv6 address assignment methods:

 Manual Assignment: An IPv6 address and other configuration parameters (e.g.,

DNS server) for the IP phone can be statically configured by an administrator.

 Stateless Address Autoconfiguration (SLAAC): SLAAC is one of the most convenient

methods to assign IP addresses to IPv6 nodes. SLAAC requires no manual

configuration of the IP phone, minimal (if any) configuration of routers, and no

additional servers. To use IPv6 SLAAC, the IP 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 IP 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
