IPv6 Testing on Apple Personal Hotspot

I have IPv6 set up and running on my home network, but there was some testing I wanted to run remotely. My local Starbucks WiFi isn’t running IPv6 according to my quick test with https://test-ipv6.com/

The same test from my iPhone on TMobile shows it’s running IPv6 by default.

I had read somewhere that Apple supported IPv6 on the personal hotspot through a loophole in the netmask routing algorithms used by most providers..

When I tested the local network connection on my computer while connected to the Apple Personal Hotspot, it appeared to be running IPv6.

Unfortunately when I connected to my phone from my computer via the personal hotspot, I wasn’t able to get positive IPv6 results. Obviously the hotspot was working since I was able to get to the test site via IPv4 without issues.

I’d read “RIPE NIC: ‘In Five Weeks We’ll Run Out of IPv4 Internet Addresses’ “ earlier today and have always been interested in understanding more of the nuances of using IPv6 compared to IPv4. Getting Ready for IPv4 Run-out has more information on how they are allocating IPv4 addresses..
