Neat! Fly’s internal DNS has been going through quite a few road bumps, of late.
Btw, I almost sent a pull-request for flyctl to let its users ssh
into a vm using private ip and as fate would have it, this is already supported (code).
For future:
$ flyctl ips private
ID | REGION | IP
-----------*--------*-----------------------------------
ddddeeee | aws | fdaa:0:aaaa:bbb:cccc:dddd:eeee:2
$ flyctl ssh console "[fdaa:0:aaaa:bbb:cccc:dddd:eeee:2]"
