I also remembered a case where just PersistentKeepalive won't save you, and
periodic DNS resolution on clients becomes mandatory. It is when the server's
physical location gets a power cut. On new boot-up (and router power-on) it
gets a new IP from the ISP, and has no idea where all the clients are. The
communication is broken until clients recheck the DNS record and update the
server's endpoint from that. WG does not do this on its own.
