Google has fixed an IPv6 fragmentation handling problem in their Public DNS Service.
In part two of his IPv6 fragmentation research posts, Geoff Huston turns his attention to measuring the packet drop rate when sending fragmented packets to IPv6 end hosts.
Is IPv6 fragmentation a fixable problem in the DNS, and if so, how?
Geoff returns to the subject of IP packet fragmentation, this time looking at how IPv6 has changed the behaviour of packet fragmentation and discussing the concern of whether IPv6 can handle big packets.
Geoff Huston examines IP packet fragmentation in detail looking at the design choices made by IPv4 and IPv6.
