A nice place to discuss rumors, happenings, innovations, and challenges in the technology sphere. We also welcome discussions on the intersections of technology and society. If it’s technological news or discussion of technology, it probably belongs here.
Remember the overriding ethos on Beehaw: Be(e) Nice. Each user you encounter here is a person, and should be treated with kindness (even if they’re wrong, or use a Linux distro you don’t like). Personal attacks will not be tolerated.

I 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.
Totally OK way of doing it. You basically manually implemented the protocol APIPA uses to allocate 169.254 addresses.
Have you never just run an nmap of the whole network and made a list of ip addresses that are occupied?
You could, but that information gets stale pretty quickly and is tricky to do with the ACLs.
ah yes the good old "gonna use manual addressing because lmao" and then the good old "man i wonder which IP sets i have used already"
my beloved.
