This testvar’s default value is computed dynamically and may not always be the value below. Please see the testvar’s description for details.
This parameter specifies a free IP address used for WAN-side renumbering tests. This IP address must be on the same network as the DUT’s WAN interface and next-hop gateway.
If not defined, this testvar defaults to the next address after wanIspAssignIp. For example, if wanIspAssignIp is 220.127.116.11 then wanIspNextIp would default to 18.104.22.168.
