Hi Brian. Ni problem. The server may tell the client (dig; please not nslookup) information about where the answer came from, if 'minimal-responses' is set to "no". Usually clients don't need to know that, so please take a look at how m-r works:

Greg, David, Thanks, much easier than what I thought it would be. I have two "root" servers so I went with this format, allowing a round robin selection. Essentially this, sorry trying to be vague on the IPs. @ 518400 IN A xx.yy.zz..7 @ 518400 IN A xx.yy.zz..8 . 518400IN NS @

Hi Brian R, I built a lab to investigate DNS cache poisoning with custom root servers, no DNSSEC. What you're trying to do is possible in production I'm just not sure it's recommended. You will need to update your root.hints (or whatever file name you're using for the root hint zone) file to

We have just upgraded the "bind-esv" repository from BIND 9.16.50 to BIND 9.18.27, i.e. the same version as in the "bind" repository. We will try to keep everyone informed about further major version upgrades in our package repositories in the coming months. -- Best regards, Michał Kępień --

Hi Sami. If you can, I would set up a new BIND (test) server running the current code - 9.18.27 - next to your current production system and compare how they behave: current code uses NS queries for qmin rather than _... A queries. There may still be failures, but this would allow you to pinpoint

Hello Thank you for your response. I have configured qname to disabled for now. Once the issue is resolved, I will set it to relaxed. I have provided a download link for the log files and a dig +trace test for more details on this issue, which I do not think is related to BIND or its
