          Generation of IPv6 Atomic Fragments Considered Harmful


   This document discusses the security implications of the generation    of IPv6 atomic fragments and a number of interoperability issues    associated with IPv6 atomic fragments.  It concludes that the    aforementioned functionality is undesirable and thus documents the    motivation for removing this functionality from an upcoming revision    of the core IPv6 protocol specification (RFC 2460).
