BOGUS domain which is not BOGUS?

Please follow the below template, it will help us to help you!

Expected Behaviour:

www.teleman.pl should not be listed as BOGUS domain when DNSSEC is activated in piHole

Actual Behaviour:

piHole shows "BOGUS" status for domain www.teleman.pl. Trying to "dig" the domain with either pdns-recursor or Google's upstream server does not indicate any DNSSEC problems. Here is the output:

resolution with piHole: dig www.teleman.pl @127.0.0.1 +dnssec +multi

So it seems to me that there is something going wrong on piHole side...

Thanks for help!

DNSSEC Analyzer test result.

For me everything is green besides the last section (which includes red entries in almost all domains I tested). Funny thing is that the first time I tried that there were some timeouts listed in first and second sections.

Can you try to repeat the query on posted page? Maybe this is something related to temporary unavailability...?

Thanks!

One more information that might be important:

My local pdns-recursor is configured in the following way:

dnssec=validate
hint-file=/etc/powerdns/named.root
local-address=127.0.0.1
local-port=5454
query-local-address6=::

That means it also validates dnssec entries. In case of www.teleman.pl it returns a valid entry (as posted above). In case DNSSEC would fail, it would also return a SRVFAIL. So why is piHole behaving different here?

Thanks!

Thanks for the answer!

The disadvantage here is that in the query log of piHole we will never see the dns security status any more, but I guess this is something I can live with :slight_smile:
