101 * The current Protocol Numbers list says that the IP protocol number for
102 * mobility headers is 135; it cites draft-ietf-mobileip-ipv6-24, but
103 * that draft doesn't actually give a number.
105 * It appears that 62 used to be used, even though that's assigned to
106 * a protocol called CFTP; however, the only reference for CFTP is a
107 * Network Message from BBN back in 1982, so, for now, we support 62,
108 * aas well as 135, as a protocol number for mobility headers.
