IPv6 specifies a model of a subnet that is different than the IPv4
subnet model.  The subtlety of the differences has resulted in
incorrect implementations that do not interoperate.  This document
spells out the most important difference: that an IPv6 address isn't
automatically associated with an IPv6 on-link prefix.  This document
also updates (partially due to security concerns caused by incorrect
implementations) a part of the definition of "on-link" from RFC 4861.
