DNS does not know what a "device" is. It's like a phonebook, it assigns names to numbers and doesn't care if some live in the same house or not.<br><br>What is the proper way? I explained it. Usually, the proper way is to avoid assigning different IP addresses to the same name.<br><br>In your specific case, use names like<br>Deb12dell-eth0 <-> ip1<br>Deb12dell-eth1 <-> ip2<br>Make the names unique.<br><br>I think DNS may be treated in networking forums. Unbound is an implementation of a dns server, besides bind and many others. Once you know what you want to do with DNS, only then can you choose what server you want to use, and then find out how to configure it. You may be doing this the wrong way by trying to configure a server without understanding the protocol.</div><br><br><div class="gmail_quote"><div dir="auto">On December 25, 2023 2:05:27 AM GMT+01:00, Jon Murphy <jcmurphy26@gmail.com> wrote:</div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
