Hi all,
I have the problem with Unbound Version 1.7.3, compiled on FreeBSD 11.2,
that it won't give the ANSWER SECTION for some hosts, like github.com.
For most hosts it will resolve properly and give this for example:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 56138
;; flags: qr rd ra; QUERY: 1, ANSWER: 1, AUTHORITY: 0, ADDITIONAL: 1
But for github.com it will give this:
;; ->>HEADER<<- opcode: QUERY, status: NOERROR, id: 57234
;; flags: qr rd ra; QUERY: 1, ANSWER: 0, AUTHORITY: 8, ADDITIONAL: 9
;; OPT PSEUDOSECTION:
; EDNS: version: 0, flags:; udp: 4096
;; QUESTION SECTION:

The unbound.conf is simple enough:
server:
interface: 0.0.0.0
access-control: 192.168.20.0/8 allow
access-control: 192.168.179.0/8 allow
private-address: 192.168.20.0/8

forward-addr: 46.182.19.48 # Digitalcourage
forward-addr: 194.150.168.168 # AS250.net Foundation
This looks like a bug, for this unbound.conf works properly with
Unbound Version 1.5.10 on the same machine.
Hints to solve that are appreciated. Thanks!
Best regards
Oliver
