<p class="MsoNormal">Hi All,<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Quick question.. I don’t have ipv6 in my office.. but where I’ll be deploying has IPv6.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">So a configuration like<o:p></o:p></p>
<p class="MsoNormal">setLocal('<ipv4>:53')<o:p></o:p></p>
<p class="MsoNormal">addLocal('<ipv6>:53')<o:p></o:p></p>
<p class="MsoNormal">setACL({'0.0.0.0/0','::/0'})<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">newServer({address='<internal v4 IP>:200',name='authv4'})<o:p></o:p></p>
<p class="MsoNormal">newServer({address='<internal v6 IP:200',name='authv6'})<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">The question is. Incoming ipv6 dns queries.. will it forward via the authv4 server or the authv6 server IP?<o:p></o:p></p>
<p class="MsoNormal">This is for the purpose of statistics. I want to be able to know how much v4 and v6 queries are arriving.<o:p></o:p></p>
<p class="MsoNormal">As far as I know.. as of 1.4 of dnsdist it does not have v6 statistics. So I have to rely on the auth server for statistics.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">One other thing I discovered.. under load testing.<o:p></o:p></p>
<p class="MsoNormal">You can only have 4 threads specified, any more then that it will have almost 0 request to threads >4.
<o:p></o:p></p>
<p class="MsoNormal">Where the 4 main threads can be maxed out.<o:p></o:p></p>
<p class="MsoNormal">An example of such is<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">I have 8 (newServer) threads to the auth server. The auth server directly can handle 270K qps.<o:p></o:p></p>
<p class="MsoNormal">If I run 2 instances of 4 threads each.. total goes to 200K.. and so on.<o:p></o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">Thanks a lot for your attention.<o:p></o:p></p>
