Yesterday I found that some fqdn could not resolved by my PC. I check the IPfire and see that my two DNS shows ‘failed’ when checking. They were from Digitalcourage and I found that they are demissioned. So I choose some other DNS ( 185.95.218.42 and 5.9.164.112) and try again … same error. Ooops?!
I added two more DNS (9.9.9.9 (Quad9) and 89.233.43.71 (Digitale Gesellschaft Schweiz)) and try again. Now DNS is working. But if I check the DNS in IPfire I get a ‘failed’ for 185.95.218.42 and 5.9.164.112. For 9.9.9.9 and 89.233.43.71 I get a ‘OK’.
If I use dig at my PC I get the same results. If IPfire shows ‘failed’ a dig in VT shows a ‘timed out’
Today this behavior is the same. I could not believe that these two DNS servers are offline so a long time. Is there way to get more info about the status of this DNS?
Can anyone confirm that these both DNS are unreachable?
I also checked my logs for any SERVFAIL messages and in the last three weeks there have been zero and before that about 10 in 2 weeks so they have not had any problems that I have experienced.
I am using the TLS protocol for the DNS communications.
If you are still getting an error with some of them then hold the mouse pointer over the error word for a short time and a pop box will show a message for the problem being experienced.
You can also look in the wui logs menu under System Logs. Select “DNS: Unbound” in the drop down box for section and press Update and you will see the logs. This should give additional information on the error message.
