Hi,
Im wondering how Unbound users are handling DGA and DGA like attacks.
Im running 20 Unbound servers and around 20% of response are NXDOMAIN, for
queries coming from my clients.
Anyone experienced this kind of attack before ? if so, how do you protect your
servers against it ? is there somet

Im having the same issue here with my servers. several queries fails when
using my server's source IP but, Google public DNS return an answer.
my workaround was to forward those queries to 8.8.8.8 using forward domain.
i wonder if there's a way to find what's causing those SERVFAIL.

Hi folks,
We have a situation here with Unbound, during internet outage for an hour or
so, Unbound keeps replying with server servfail for valid domains even after it
gain access to internet, to fix this, i have to reload or restart Unbound.
This happens every time we lose internet for more th
, 1.4.20 is from 2012. Perhaps the newer version
does not have this issue in this manner.
You can also flush the infra cache, with unbound-control flush_infra
all, that way you don't lose the DNS cache.

Hi,
How can i measure the query response time ?
unbound-control stats histogram is only for recursive requests right ? how can
i measure the average response time of the cached queries ?
Thanks
