This entry defines the address of the DS-Lite gateway, the so-called Address Family Transition Router (AFTR). Enter a valid value from the following selection:
- One IPv6 address (e.g. 2001:db8::1)
 - An FQDN (Fully Qualified Domain Name) that can be resolved by DNS, e.g., aftr.example.com
 - The IPv6 unspecified address "::" determines that the device should retrieve the address of the AFTRs via DHCPv6 (factory setting).
 - An empty field behaves the same as the entry "::".
