JPNIC wants to grasp the real situation of the world. We would be grateful if you could answer the survey below by July 10th. https://docs.google.com/forms/d/e/1FAIpQLSfgxaDgDwHbWOv7RNbHYTRbNHQa_HFCPv0… It would be highly appreciated if you could kindly provide us with your input.

It's not clear to moe at all what value larger packets provide. You may avoid the occasional TCP transaction. But then there are weird corner cases, such as the difficulty of serving UDP over IPv6 in a stateless fashion, while still supporting fragmentation.

Or you can avoid fragmentation in the first place, which includes ignoring ICMP Fragmentation Needed But DF Bit Set messages. Unbound does that if you tell it to use it a buffer size which is sufficiently small. Theoretically, even with a 1200-byte EDNS buffer size, there could be IPv4 network paths which trigger fragmentation, but those will be unusual. Another benefit of this change is that many of the ENDS-related problems go away.
