IPv6 is the next generation network layer protocol that was designed as a replacement
for the current IPv4 protocol. IPv6 was 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, which consists 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.
IP phones support IPv4 only addressing mode, IPv6 only addressing mode, as well as an
IPv4/IPv6 dual stack addressing mode.
IPv6 Address Assignment Method
IP phones support the following 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 on the IP phone, it is important that the IP
phone is connected to a network with at least one IPv6 router connected. This
