    abstract =  {The Prefix Information Option in the IPv6 Neighbor Discovery Router Advertisement message defines an 8-bit prefix length field. Prefix List entries are created using the prefix length in the Prefix Information Option. The Conceptual Model of a Host described in RFC 4861{[}RFC4861{]} does not clarify behavior of a host, when a short prefix length is received. This document updates RFC 4861(if approved), and clarifies that hosts SHOULD NOT accept prefix length shorter than /64.},
