<div dir="ltr"><div>Hi David.</div><div><br></div><div>I find your configuration a bit bizarre because you say you don't want recursion, yet you have both "recursion yes;" and "forward first;' (which is the default anyway, so this statement is redundant).</div><div><br></div><div>"recursion yes;" says to attempt recursion unless something else (like forwarding) says not to. So try setting that to "no".</div><div><br></div><div>"forward first'; says to recurse if forwarding fails, which sounds like exactly what you don't want to happen.</div><div>I am not sure what the behaviour is if you define zone "." and then (presumably) give it a null list of hints. it may be that this is ignored and built-in root hints used instead. A pcap should show this.</div><div><br></div><div>With so many forwarders (quite a lot!), why should it be that forwarding ever fails completely? The usual point of forwarding is to offload queries to somewhere reliable, not deliberately unreliable or likely to fail.</div><div><br></div><div>Hope that helps.</div><div>Cheers, Greg</div></div><br><div class="gmail_quote gmail_quote_container"><div dir="ltr" class="gmail_attr">On Fri, 5 Sept 2025 at 19:30, Reynolds, David <<a href="mailto:DReynolds@epiqglobal.com">DReynolds@epiqglobal.com</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="msg5000778473581881929">
