[Pdns-users] About unreachables this indicator

[abang at t-ipnet.net]

Hello 姜伯洋,

Logging of "unreachables" is not possible as far as I know. Although it would be a handy feature.
You could try "rec_control trace-regex '.*'". But this produces a huge amount of log and possibly decreases the Recursor performance.
