What is a transitory IPv6 address?

Verizon assigns an IP from their pool. If the wireless router reboots it
may or may not get the same apparent external address.

That would be a dynamic address. Same like for IPv4, only in IPv4 that
complexity is hidden behind another layer of complexity named NAT.
Without NAT, you couldn't use more than one device on your LAN because
your ISP is unlikely to assign more than one IPv4 address to your
network. A clueful ISP would assign a /56 IPv6, which gives you enough
addresses for 256 internal networks, each one with more addresses than
you could afford the power to run computers on.

 

Even better, it looks like I'm in Montrose Colorado today.

 
Your ISP is stupid and didn't correctly register their IPv6 networks.

I'll say it again. slowly. Verizon wireless. Figure out how CGNAT works.

IPv6 doesn't use NAT nor CGNAT.

The edge server may be in Colorado or Utah. I've even seen Kansas. If I go
to a site like https://whatismyipaddress.com/  it's going to reflect where
the server is.

Right, because ISPs are stupid. Geo-IP is stupid as well, but alas.
