Used to transfer DHCP (Dynamic Host Configuration Protocol) messages between clients and
servers when they are on different subnet domains. DHCP option 82 allows a DHCP relay agent
to insert specific information into client request packets when they are forwarded to the
DHCP server. When reply packets are sent to a DHCP client, the information will be removed.
The DHCP server can use this information to implement IP addresses or other assignment
policies. Specifically, the option works by setting two sub-options: Circuit ID (option 1)
and Remote ID (option2). The Circuit ID includes information specific to the circuit where
the request originated. The Remote ID carries information about the remote host.
