Any ideas how to get a client-server style VPN setup with WireGuard working with IPv6 so that it keeps working even if the public IP address of your VPN server

Any ideas how to get a client-server style VPN setup with WireGuard working with IPv6 so that it keeps working even if the public IP address of your VPN server changes? The configurations I've seen assign a statically configured IP address to a client. This works fine with NATted IPv4, but with IPv6, addresses are "public", so the client must basically know the prefix of the server to be able to configure a sane address, and if that changes, the configuration must be changed by hand.
