Comment:

 I checked using wireshark and the DNS queries are from tor's
 `dns_launch_wildcard_checks` and `dns_launch_correctness_checks`.

 Do we want to have a way of disabling external network access (including
 DNS) for test networks?

 I can imagine there are scenarios where this would be useful, but I'm not
 sure if it's a priority for anyone.
