Tailscale IP addresses - unique?


A quick question: The documentation states that Tailscale’s 100.x.x.x IP addresses are assigned uniquely.

Are they globally unique or are they unique within each network?

ie would it possible (however unlikely) for there to be an IP address collision between my use and another user?



They are globally unique.

…for now. We reserve the right to do a bit more magic as the total network size inevitably grows too large to fit in that subnet. This is not too hard since the “sharing points” between networks are well contained.
