Hey, I know that guy.<br>
<br>
These are some long-running measurements related to a study on IPv6 <br>
hitlists: <a href="https://ipv6hitlist.github.io/" rel="noreferrer" target="_blank">https://ipv6hitlist.github.io/</a><br>
<br>
Measurement IDs are:<br>
<br>
<a href="https://atlas.ripe.net/measurements/24304869/" rel="noreferrer" target="_blank">https://atlas.ripe.net/measurements/24304869/</a><br>
<a href="https://atlas.ripe.net/measurements/24304870/" rel="noreferrer" target="_blank">https://atlas.ripe.net/measurements/24304870/</a><br>
<br>
Probes with IPv6 will resolve the name and then run UDP and ICMP <br>
traceroutes to the address in the answer, if they get one, much like <br>
built-in measurements 6052 and 6152. They're configured to run on the <br>
frequency of one resolution per measurement every two minutes.<br>
<br>
I didn't investigate whether or how the DNS server was broken, but a few <br>
moments ago I restarted the process and I can see that it's handing out <br>
answers.<br>
<br>
Cheers,<br>
