dhcp-options - Dynamic Host Configuration Protocol options
Description
The Dynamic Host Configuration protocol allows the client to receive options from the DHCP server describing the network configuration and various services that are available on the network. When configuring dhcpd(8) or dhclient(8) , options must often be declared. The syntax for declaring options, and the names and formats of the options that can be declared, are documented here.
