Abstract:
This memo was written to make application developers and network
operators aware of the significant possibility that IPv6 packets
containing fragmentation extension headers may fail to reach their
destination. Some protocol or application assumptions about the
ability to use messages larger than a single packet may accordingly
not be supportable in all networks or circumstances.
This memo provides observational evidence for the dropping of IPv6
fragments along a significant number of paths, explores the
operational impact of fragmentation and the reasons and scenarios
where drops occur, and considers the effect of fragment drops on
applications where fragmentation is known to occur, particularly
including DNS.
