Table 14: IPv6 Setup Menu Options
DescriptionDefault valueOption
Indicates the method that the phone uses to get the IPv6-only
address.
When DHCPv6 is enabled, the phone gets the IPv6 address either
from DHCPv6 server or from SLAAC by RA sent by the
IPv6-enabled router. And if DHCPv6 is disabled, the phone will
not have any stateful (from DHCPv6 server) or stateless (from
SLAAC) IPv6 address.

Displays the current IPv6-only address of the phone or allows the
user to enter a new IPv6 address.
Two address formats are supported:
•
Eight sets of hexadecimal digits separated by colons
X:X:X:X:X:X:X:X
•
Compressed format to collapse a single run of consecutive
zero groups into a single group represented by a double
colon.
If the IP address is assigned with this option, you must also assign
the IPv6 prefix length and the default router.
