How to handle DHCP reservations on multi NIC (Ethernet&WiFi) devices?

[janwiesemann]

I'm currently trying to move all my devices to a reserved DHPC4 entry for the "Denie unknown clients" option. Sadly, I've run into an issue when im adding entries for devices with multiple network interfaces. My MacBook ist connected through WiFi and Ethernet at the same time. With a floating entry, it's possible for a device to register multiple addresses with the same host name. This can be validated though `dig` or the `/status_dhcp_leases.php` page. If I try to add these entries manually, I'm unable to do so, since it's not allowed to add two entries with the same hostname.

So, How am I supposed to handle such cases?

Yes, I could use a different hostname for my second NIC but I don't like this approach.
