Update the built-in root hints file: this hasn’t been done in three years, and b.root-servers.net’s IP addresses have changed since (see [1]). This is to make sure that we don’t send traffic to IP addresses belonging to _former_ root servers (see for example [2] for the case of J-root). I think this also reveals an oversight in our release procedure: we ought to make sure that every release of Zonemaster ships with a fresh and up-to-date root hints file. I don’t think this is currently the case. Unit test data needs to be rerecorded as well. This is done except for t/old-bugs.data; that file cannot be updated easily.
