What are reasons to use a certificate for an IP? Why wouldn't you use a name?

Someone already mentioned that it's needed for Discovery of Designated Resolvers (DDR) for DNS-over-HTTPS. Anything else?

Names cost cash; maybe you don't need/want one.

xip and https://nip.io are common workarounds for this.

I can't remember if one or both are in the mozilla list of public domain prefixes though.

If you need https, but whatever device you want to serve to doesn't let you use hostnames.

Like what?
