UI does not allow multiple MAC for same DHCP address
The UI does not allow multiple MAC addresses to be assigned the same DHCP address, even when using different hostnames. Several forum posts and a previously closed issue, this should be allowed given that a different hostname is used.
Unfortunately, it appears that the UI is blocking this.

As the discussion in some of those former tickets and posts implied, the IP address can be reused as well as the hostname. I removed both uniqueness checks from the page and the configuration appears to function properly.
Needs some more testing/confirmation but it looks OK here.
