Options are variable length octet strings. The first octet is the option code, the second octet is the number of following octets and the remaining octets are code dependent. For example, the DHCP Message type option for an Offer would appear as 0x35,0x01,0x02, where 0x35 is code 53 for "DHCP Message Type", 0x01 means one octet follows and 0x02 is the value of "Offer".
