What is this "wan0_xipaddr", and why is it showing up in the GUI?

Router: ASUSWRT-Merlin RT-AC68U 384.15_0

My ISP has me double-NATed, so I've got both an internal IP address and a public IP address.

I can see my internal IP address with:

nvram get wan0_ipaddr

I can see my public IP address with:

nvram get wan0_realip_ip

But, when I check the "Internet status" via the router's GUI, I see the correct internal IP address and an address below it that is not my public IP address, 169.254.xx.xx.

That 169.254.36.118 address can also be found with:

nvram get wan0_xipaddr

Questions: What is the wan0_xipaddr, and why is it displayed in the GUI where I'd expect to see wan0_realip_ip?



This may or may not be related to the GUI perpetually showing "Lease time = Renewing...", and, "Lease expires = Expired", even though I'm connected and online.

You are using PPPoE so the 169.254.xx.xx address is the local connection to the modem. That's normal. It can be disabled at WAN > Internet Connection > Special Requirement from ISP > Enable VPN + DHCP Connection.

The 100.64. address would normally be your "public" (WAN) IP address, although in this case it is actually a CGNAT address.
