> I guess really the bigger issue here is the dynamic nature of the prefixes. If I could go log into IANA and click a button and get assigned a /48 then log in to my ISPs' sites and attach it to my connection and be on my way... I'd deploy it today, no problem.

Yes, this right here. It should work like a phone number where you can take it from provider to provider. You setup your gateway with your IPv6 prefix and then go.

Problem is all the technical and non-technical stuff to actually make that work.

- Verifying ownership of the prefix (rPKI or IRRs) and which ASNs are allowed to advertise it.

- Limiting allocations to someone? I guess phones solve this with SIMs

- Getting your ISP to route the traffic to your device

- Getting the device to announce it with RAs

- Dealing with asymmetric return routing over a slow "path" since it could be multi-homed

- Dealing with routing aggregation since IPv6 routing tables would explode with all the /56s in there

Maybe bring back Mobile IPv6? https://en.wikipedia.org/wiki/Mobile_IP
