You need to know something about the protocol. Likely your network
department half set up IPv6 and then stopped doing it, leaving it with
semi or non-working IPv6. Of course this is bound to fail.

IPv4 should have continued working seamlessly.

Perhaps the correct thing to do would have been to make it work company
wide but nobody is going to sign off on an expensive project to fix
something that ain't broken -- yet.

IPv4 IS broken. It has been broken for 30 years, in a way that made
many people think that a network protocol must be broken to work.

Since my internet connection is through Verizon wireless I have both IPv4
and IPv6 external addresses. They're transitory and while I can find out
what they are I don't have any need to know.

What is a transitory IPv6 address?

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

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

The devices on the WiFi LAN also have IPv6 addresses along with IPv4.
However if I want to ssh, sftp, or vnc into one of them, I know and use
the IPv4 address.

Use DNS.
