SERVFAIL IPv6 debugging

Hi bind-users, Apologies if this is inappropriate for this list. I am trying to debug a failure to resolve an external name. It appears that when I try to resolve the name ec.europa.eu over IPv6 using either dig +trace or with a caching named that it sometimes fails: [nimbus]root: dig -6 ec

Upgrading from 9.14.12 to 9.16.4 - with existing DNSSEC zones

I am using DNSSEC for more than 5 years now (never had a problem so far), but after upgrading to the latest bind-9.16.4 the verification fails using Verisign's DNSSEC Validator. I reverted back to 9.14.12 and everything works as expected. First I started upgrading my secondary DNS-Server (p

Re: Negative Cache won't go!

Not unusual in my experience. Probably find the dns is badly configured - at a guess different ns records at root servers or missing/badly configured ns records. Check the dns of the domain out with dnsstuff.com and fix any errors. Probably find it works then. Duncan Alans wrote: Hi

RE: Host/nslookup/dig queries wrong server

Host/nslookup/dig queries wrong server

r. I had expected both would be running the same version of bind and am surprised that they are so different. Any idea how the correct behaviour can be reinstated and why it is happening. Apologies if this is the wrong place to ask but it would appear to be a bind issue. Thanks D
