IPv6 Test Preferences

Global IPv6 Address: The Global IPv6 Address (GUA) is used to
communicate with on-link neighbors and for global communication
with hosts outside the subnet.
Mode

None disables the Global IPv6 address and the Default Gateway
address.

Stateless Auto allows automatic generation of the IPv6 address
based on the Link-local address interface ID and the prefix
obtained from router advertisements. If no Interface ID has been
obtained for the Link-Local address, the Global address will not be
generated. The mode Stateless Auto is selected by default.

Static allows to enter the IP address. The default address is
2001::[Interface ID], where [Interface ID] is generated from the
source MAC address.
Interface ID Coupled: Available when the Static Mode is selected, it
allows to couple the interface ID of the Global address to the Link-local
source address. The Global address interface ID will match the
Link-local address interface ID. The Interface ID Coupled check box
is selected by default.
Prefix Mask: Available when the Static Mode is selected, it allows to
specify a prefix that defines the subnet. For example:
Note: When the Global address mode configuration is Stateless Auto, the prefixes
are obtained from the Router Advertisement messages. When no prefix is
obtained, the Global address is unspecified and the next-hop is assumed to
be inside the subnet.
