Installing foreman on alterway02

I'm trying to install foreman on alterway02, but what IP space do we have? I noticed it's in a /24 block, but I doubt we can fully use that given the shortage of IPv4 space. I also limited the NFS access to just that /24 block instead of 0.0.0.0/0, but I'm sure we could limit it a but further. Lastly we should figure out how to manage DNS. It would be great if foreman could create entries.
