What happen if tailscale run out of IP addresses?

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.
|Network Address:||
|Usable Host IP Range:| -|
|Total Number of Hosts:|4,194,304|
|Number of Usable Hosts:|4,194,302|

We have introduced Ipv6 support from Tailscale 1.6 release.

along these lines… Are these IP addresses static?

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

I’m in favor :wink:
