Description Jason Mader 2017-09-29 17:59:59 UTC
I noticed unbound uses the default "edns-buffer-size: 4096", while FreeBSD resolver sets the receive buffer size UDPsize=65535. It might make sense to add "edns-buffer-size: 65535" to the default unbound.conf file when it's setup to match the behavior when not using unbound.

If you think the default value is inappropriate, I would suggest taking it up with the upstream developers.
