Thank you for this explanation! Now i finally understand what the “mask” part means! Any 0s will mask the IP address in the AND operation and tell the computer that address is not part of the network.
Glad I could help with learning a new thing! If you are curious on anything else networking, I’m a Network Engineer by trade and happy to share knowledge.
That’s another private range that was added for Carrier-Grade NAT that is part of RFC6598. It’s a non-Internet routable 100.64.0.0/10 subnet for things like WISPs, Satellite providers like Starlink, Tailscale, and cellular providers that are strapped for IPv4 addresses.

Ok one last question: did tailscale have to buy the 100.100.100.x range, or is that available to anyone and they are just the only user i know?
