What does the Client-ID represent in the DHCP binding output?

  • The client's IP address
  • The VLAN ID
  • The DHCP pool name
  • The client's MAC address with a prefix

Explanation: According to the sources, the Client-ID (or client identifier) represented in DHCP binding outputs is a unique string used by the server to identify a specific host. For devices using Ethernet, this identifier typically consists of the digits 01 followed by the client’s physical MAC address. This 01 prefix indicates the media type and causes the dotted hexadecimal notation to appear slightly different from a standard MAC address. Identifying the correct Client-ID is a critical step when configuring manual address bindings to ensure a specific IP address is consistently reserved for and assigned to the intended device.
