<p>Hello,<br> <br>I am Alberto Garcia, Coms admin in a ISP. I dont really know if you can answer this question, but IANA has sent me to you... so this is my problem:<br> <br>we are sending inverse queries to these blackhole servers:</p>
<p>"<a href="http://blackhole-1.iana.org">blackhole-1.iana.org</a>" and "<a href="http://blackhole-2.iana.org">blackhole-2.iana.org</a>",</p>
<p>The inverse queries are asking for private addresses, this traffic is <br>normal in our network so there is not any abuse. My problem is that i <br>cant get any response from these servers and the normal operation for <br>
these queries is (from the web <a href="http://www.iana.org/abuse/faq.html">http://www.iana.org/abuse/faq.html</a>):</p>
<p>"Since the RFC 1918 addresses should never be used on the public <br>Internet, there should be no names in the public DNS that refer to them. <br>Hence, an inverse lookup on one of these addresses should never work. <br>
The IANA blackhole servers respond to these inverse queries, and always <br>return an answer that says, authoritatively, that "this address does not <br>exist". Because of the caching noted above, this is far better than <br>
simply not responding at all, so the blackhole servers are provided as a <br>public service."</p>
<p>I have also tried to do a query from my PC in my home, and i didnt get <br>response.</p>
<p>> 10.208.1.1<br>Servidor: [195.175.48.42]<br>Address: 195.175.48.42</p>
<p>DNS request timed out.<br> timeout was 2 seconds.<br>*** La petición a [195.175.48.42] a caducado</p>
<p>Can you tell me if there is any problem with your blackhole servers ? The problem is mine?<br> <br>Thank you in advance</p>
