How to get router id (ip address)

[thekioskman]

To send the packets we need the router ID, which is the IP address of our current router. The parameter to pwospfquery(ipv4 ) seems to be the id of the router we want to find a path to. So how do we get our own IP address? If we use std::optional<ipv4_t> ip = getIPAddr(port); which port should we use?

You should use port 0 as stated in the documentation.
