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.,36066.msg186013.html#msg186013

Unfortunately, it appears that the UI is blocking this.

Do not apply a DHCP static mapping uniqueness test for hostnames or IP addresses. The DHCP daemon allows the entries to be duplicated provided they have unique MAC addresses or identifiers. Fixes #8220

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.

Also: This problem was introduced over 4 years ago when a contributor added the IP address check instead of removing "IP" from the input error text in ce13cc5f8f661f4ef0d24e237a83d4caccea6a11
