<div dir="ltr">Hi Brian.<div>Yes, you can define your own hint zone and tell BIND to use it. The contents (I called the file "db.root" but the name is your choice) could be as simple as:</div><div><br></div><div>@ 300 IN A 127.0.0.3<br>@ 300 IN NS @<br></div><div><br></div><div>which says for this zone (which will be called ".", coming next) the NS is the same name and its IP is 127.0.0.3, which happens to be another instance of BIND I have running. Your file would contain the names and IPs of your internal roots.</div><div><br></div><div>In the config, define the hint zone like this:</div><div><br></div><div>zone "." {<br> type hint;<br> file "db.root";<br>};<br></div><div><br></div><div>That should be all you need.</div><div>Cheers, Greg</div></div><br><div class="gmail_quote"><div dir="ltr" class="gmail_attr">On Wed, 26 Jun 2024 at 15:58, Cuttler, Brian R (HEALTH) via bind-users <<a href="mailto:bind-users@lists.isc.org">bind-users@lists.isc.org</a>> wrote:<br></div><blockquote class="gmail_quote" style="margin:0px 0px 0px 0.8ex;border-left:1px solid rgb(204,204,204);padding-left:1ex"><div class="msg-6091174232746097928">

<p class="MsoNormal">We would like to use root servers within our organization rather than the actual root servers.<br>
I updated the hints file with the names and IPs of our servers, but we seem to still access the official root servers.<br>
<br>
Wondering how I ignore the internal/build-in hints and have my own file.<br>
<br>
Wondering if replacing the IP addresses in the db.cache file with a round-robin of my internal IP addresses isn’t the answer.<br>
Not elegant but perhaps would work?<br>
<br>
Is there a supported way to do what I want to do – we do not want an forwarding only server, we do serve a good number of internal statis and dynamic zones but also want to resolve non-domain addresses or addresses we lack forwarder zones for from a ‘root’
