I can get VOIP calls behind a NAT without cell service. I'm asking how is that possible. Is the router somehow part of the same AP as cell service?

I was wrong, I didnt realize ipv6 was 128bit. Still stuff like IPFS and git hashes are larger than 128bit to prevent collisions so there is a precedence for using larger address spaces when not having address reuse.
Yep, and I can verify my phone number didnt change when roaming, people could still call me.
The IP doesn't persist across network hops (cell tower to cell tower) and the MAC address doesnt have one verified owner. A phone number is both verified having one owner and persists across network hops.
Even paying for a static IP its not like a phone number which is discoverable behind a NAT without extra router configuration.
no need for an endpoint to be directly exposed
If I were an engineer in the past, trying to send a message back to an endpoint (e.g. a server response) I would've reached for everything having a static IP, same as the EID system with phones, instead of the DHCP multi-tier NAT type system with temp addresses.
I'm all but certain they didnt do it for privacy reasons at the time.
Same people who decide phone numbers and domain names. We already have central registries, why does it being a computer make it harder to have a central authority?
Solid answer, thanks! You deserve all the upvotes that were, instead, for some reason, given to the guy that just said "I think its a MAC address"
I meant "in the same way that phone numbers are unique to phones (not perfectly unique, some phones have dual Sim, some have no sim, sometimes a Sim changes numbers after contacting the provider, etc)"
Its just typing all that^ in a title is kinda long.
EUI-64 IPv6 (and why its not a reality) though is kinda what I'm curious about. But not really because, even under that spec, its still not static like a phone number. I want to know why networks were not created in a way where I can send a message to a laptop regardless of what WiFi its connected to (assuming it is connected and online).
Cool, I'll have to look that up!
