Maybe by interfacing with the router?

You can somehow send some kind of query to the router using router protocols, and it’ll process a return packet with the wan ip address I think, per wan ip address attached to the router

Or you can flat out make a standard for all routers to adhere to when returning wan ip addresses, along with others stuff like live latency checks or some kind of network security module

Or someone awesome can implement some kind of protocol or handshake method for linux router distributions to return the wan ip address directly from the linux router

I think my packet thing will work

You can send a packet through the lan network, and it should return the wan ip address, I think, just through multiple layers or something
