DNS Flag Day 2020: The default EDNS buffer size has been changed from
|
|
4096 to 1232 bytes. According to measurements done by multiple
|
|
parties, this should not cause any operational problems as most of
|
|
the Internet "core" is able to cope with IP message sizes between
|
|
1400-1500 bytes; the 1232 size was picked as a conservative minimal
|
|
number that could be changed by the DNS operator to an estimated path
|
|
MTU minus the estimated header space. In practice, the smallest MTU
|
|
witnessed in the operational DNS community is 1500 octets, the
|
|
maximum Ethernet payload size, so a useful default for maximum
|
|
DNS/UDP payload size on reliable networks would be 1400 bytes.
