Hi, Ray: The values used by the "IP Version" field should be specified: IP Version: The IP protocol version number used by the client. Since the field is 4 bits long I would guess this field happens to be the same as the version field in the IP header [0], maybe with the restriction that the field can only take on the values 4 and 6?
