prefix: A variable-length field containing an IP address or the
prefix of an IP address. An IPv4-mapped address [RFC4291] must
be used to represent an IPv4 address as a prefix value. The
prefix should be left aligned, big-endian, and zero padded on
the right up to the next octet boundary. So the length of this
field should be between 0 and 16 bytes
is ambigious on the encoding of 2002:1234:8734::/64
is it:
40:20:02:12:34:87:34:00:00:00:00:00:00:00:00:00:00
or
40:20:02:12:34:87:34:00:00:00:00:00:00:00:00:00
or
40:20:02:12:34:87:34:00:00:00:00:00:00:00:00
or
40:20:02:12:34:87:34:00:00:00:00:00:00
or
40:20:02:12:34:87:34:00:00:00:00:00
or
40:20:02:12:34:87:34:00:00:00:00
or
40:20:02:12:34:87:34:00:00:00
or
40:20:02:12:34:87:34:00:00
or
40:20:02:12:34:87:34:00
or
40:20:02:12:34:87:34
All appear to be legal. It would be cleaner if the
floor((prefix-len+7)/8) gave the number of octets in
the prefix field.
