IIRC, when you disable dhcp on the network, modern cloud-init (like debian 12/Ubuntu 22.04) will configure the IP on your instance at boot time after doing a metadata network request.

That just works, but it depends on OS. [...]

Cloud-init can also get network configuration from a mounted configdrive (if you pass the right server create options so it gets one), and skip requesting metadata over the network that way. -- Jeremy Stanley
