Sure it can… That’s just software.
With careful design by real experts, it is possible to design such a protocol even with IPv4 but IPv6 "committee" naturally abandoned to do so with IPv6.
What’s missing? We already have DDNS and DHCP is already capable of doing what’s needed to update the DNS server there. If you don’t like DDNS, then there are relatively simple ways to script DNS updates for prefix changes as well. Owen
