What is ctDhcpClientID?
This is the client identifier the device supplied in its DHCP request, which is normally the client's Ethernet MAC address. It lets an admin tie a lease back to a specific physical network card when troubleshooting duplicate or unexpected leases. For example, seeing 00:1A:2B:3C:4D:5E next to a lease entry confirms it belongs to the known conference-room switch rather than an unrecognized device.
