Description

This option is a single octet of decimal 255 ("FF") used to indicate the end of a DHCP options area in DHCP message packets. This option differs from most DHCP option types because it does not use a length or value field. Typically, it is used at the end of the options field to indicate that there is no more option data in a DHCP message packet. It can also be used within the message, in connection with the vendor-specific information (option 43), to indicate the end of an encapsulated vendor-specific options subfield. This option does not require configuration.
