<div> </div>
<div>I have dnsdist in front of pdns with this config:</div>
<div> </div>
<div># start_dnsdist.conf</div>
<div> </div>
<div>local public_ipaddr = "x.x.x.x"</div>
<div>local rec_ipaddr = "10.200.1.19"<br/>
local hostname = "dns01"<br/>
</div>
<div>setLocal(public_ipaddr .. ":53", true, true)</div>
<div> </div>
<div>setACL({"0.0.0.0/0", "::/0"})<br/>
</div>
<div>setECSOverride(true)<br/>
setECSSourcePrefixV4(32)<br/>
setECSSourcePrefixV6(128)<br/>
</div>
<div>newServer{address=rec_ipaddr, source="eth0", name=hostname.."-recursor", order=1, checkName="google.com.", pool="recursive", useClientSubnet=true}</div>
<div> </div>
<div>setServerPolicy(firstAvailable)<br/>
</div>
<div># end_dnsdist.conf</div>
<div> </div>
<div>For some reason my dnsdist log is flooded with these entries.</div>
