wg-dynamic project is not developed any more.
Therefore we close this topic.

Sorry I misinterpreted the issue yesterday. It is not about dynamic client IPs here (which is sadly dead), but about dynamic server IP handling.

WireGuard ships with this script:

/usr/share/doc/wireguard-tools/examples/reresolve-dns/reresolve-dns.sh

It resets the resolved IP address for the configured WireGuard server. Hence, if your server has a dynamic IP, and you run a client on a Linux/DietPi system, the above script can be run on a regular basis as needed, like every 10 minutes or hourly, via cron job or systemd unit, to keep the VPN functional without manually disconnecting and reconnecting.
