May I chime in, I feel identity type is a good idea.
But if you map DNS to other identity,
how network socket connection could work in that case/
thanks for your consideration

Findable, not reachable, even just identifiable, is what is essential for the naming system DNS.

The job of the Domain Name System, not routing or delivery system, is to map names to identity. Furthermore, identity mapped to may be of entire routing domains, aggregating nodes.

Still network location is disticnt from geographic.
I suggest that there be a networking asset, an address type, that represents network identity of nodes. And addresses of that type be resolved to by DNS name queries and be mapping to unicast network addresses.
This way DNS shall be unburdened of connectivity, routing and reachability issues related to named nodes.
