DYNAMIC HOST CONFIGURATION PROTOCOL
Dynamic Host Configuration Protocol (DHCP) can dynamically allocate an
IP address and other configuration information to network clients when
they boot up. If a subnet does not already include a BOOTP or DHCP server,
you can relay DHCP client requests to a DHCP server on another subnet.

(Option 60). This information is used to convey configuration settings
or other identification information about a client, but the specific string
