Certain lookups provide my external IP as the answer. I'm interpreting that as a failed lookup. If that's the case, then how can I get unbound to provide an actual "failed lookup" response rather than my own external IP address? </div><div><br></div><div>I've looked all over the unbound.conf site and found nothing with respect to this particular problem. The logs don't give me </div><div><br></div><div>Machine w Unbound<b># nslookup 96.94.160.167.<a href="http://sbl-xbl.spamhaus.org/">sbl-xbl.spamhaus.org</a></b><div>Server:<span class="Apple-tab-span" style="white-space: pre; "> </span>127.0.0.2</div><div>Address:<span class="Apple-tab-span" style="white-space: pre; "> </span>127.0.0.2#53</div><div><br></div><div>Non-authoritative answer:</div><div>Name:<span class="Apple-tab-span" style="white-space: pre; "> </span>96.94.160.167.sbl-xbl.spamhaus.org.aquawest.net</div><div>Address: <i>1xx.1xx.1xx.1xx </i> [<i>my external IP address]</i></div><div><i><br></i></div><div><i><br></i></div>
<br></div><div>In addition, the following yields an answer that's just wrong. I've tested this on an machine that doesn't use unbound.
