Just curious, because I found that there are only 4 million IP addresses in the range. It sounds like it is not a small number, but it is also not a large number.

100.64.0.0/10
|Network Address:|100.64.0.0|
|Usable Host IP Range:|100.64.0.1 - 100.127.255.254|
|Total Number of Hosts:|4,194,304|
|Number of Usable Hosts:|4,194,302|

Yes, they are assigned when an endpoint is given a Tailscale certificate and will not change during the lifetime of that certificate.
