I consulted with professor gpt and it seams that it’s basicly just giving the same ip address to multiple servers meaning that any of said servers can serve as that ip.
Also it seems said ips require paying large sums of money to isps. My poiny was more that with the current mainstream internet (http websockets etc) it would require you to run a local service/proxy that can interpret a global id and route to basicly any small server with said resource. Unfortunatly i dont think its possible to build such a thing that would just work across browsers if embedded into a standard webpage.
