Update - Yes Chatty Kathy tries IPv6 also
My first post only covered IPv4 because that is all I have seen.
But I just today recorded Chatty Kathy querying the name servers at ultraDNS for IPv6 address(es).
In my case, it didn't do her any good, I don't have public IPv6 enabled while testing.
But those readers who do have IPv6 enabled...
You will probably want to block her use of IPv6 in addition to the IPv4 rules above.
Just limit her to 20th Century networking and then the IPv4 rules above should be enough.
