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).

This document is a product of the IPv6 Maintenance Working Group of the
IETF.
