Have you never just run an nmap of the whole network and made a list of ip addresses that are occupied?
Comment on Low tech DHCP
Toribor@corndog.social 7 months agoI want to criticize this but I have multiple production environments with no DHCP and the process for provisioning new servers is basically “Guess an ipv4 address and if you pick one that’s already in use the build will fail and you can guess again.”
This is arguably better which is a little embarrassing.

You could, but that information gets stale pretty quickly and is tricky to do with the ACLs.

Totally OK way of doing it. You basically manually implemented the protocol APIPA uses to allocate 169.254 addresses.
