See my pseudo algorithm, I think we can sync on the fly from netbox to local pveipam (like a read cache), when we allocate a new ip. I think it's not a problem with multiple cluster with different local pveipam, if we always try to allocate a new ip from the external ip, then write it to local pveipam, for later read. Maybe it could be improve with a full sync of subnets in cron ?

(so when you'll be in vacation ^_^). If you have some early patches for this time, I'll be able to continue the work if needed. > > Yes,admin should be able to see allocated ip.
