Description

Used by a DHCP client to request specific option type values from the DHCP server. Each option type is requested and listed by a single octet value containing a valid or recognized DHCP option code for the server.

For clients that use this option type, the list can be ordered by preference, although the DHCP server is not required to return options in the order they are requested. However, the DHCP server attempts to insert the requested options in the order requested by the client.
