https://www.iana.org/assignments/_6lowpan-parameters/_6lowpan-parameters.xhtml

It says 4944, because 4944 defines how IPv6 is encoded (uncompressed) in
a 802.15.4 frame: The MAC payload begins with a dispatch byte (decimal
65), followed by the IP packet.  4944 says:

   IPv6:  Specifies that the following header is an uncompressed IPv6
      header [RFC2460].

where 2460 is a normative reference.  This is all exactly as it should
be (except that we have since learned it's not so bright to have both
uncompressed and compressed alternatives available).
