# Reduce EDNS reassembly buffer size.
|
|
# IP fragmentation is unreliable on the Internet today, and can cause
|
|
# transmission failures when large DNS messages are sent via UDP. Even
|
|
# when fragmentation does work, it may not be secure; it is theoretically
|
|
# possible to spoof parts of a fragmented DNS message, without easy
|
|
# detection at the receiving end. Recently, there was an excellent study
|
|
# >>> Defragmenting DNS - Determining the optimal maximum UDP response size for DNS <<<
|
|
# by Axel Koolhaas, and Tjeerd Slokker (https://indico.dns-oarc.net/event/36/contributions/776/)
|
|
# in collaboration with NLnet Labs explored DNS using real world data from the
|
|
# the RIPE Atlas probes and the researchers suggested different values for
|
|
# IPv4 and IPv6 and in different scenarios. They advise that servers should
|
|
# be configured to limit DNS messages sent over UDP to a size that will not
|
|
# trigger fragmentation on typical network links. DNS servers can switch
|
|
# from UDP to TCP when a DNS response is too big to fit in this limited
|
|
# buffer size. This value has also been suggested in DNS Flag Day 2020.
