I notice on one Windows 2008 R2 DHCP server the device with the first IP in the range has a strange looking Unique ID of the format


And the DNS name HP.domain.local

See screenshot. Does anyone know what this is and why it doesn't show a standard MAC for the unique ID? DHCP Screenshot

Split the string in pairs and convert hex to ascii, you will get cc3e.5f92.2bb3-Vlan-interface1, it is most probably one of your HP switches registering.
