ip6.arpa PTR queries still sent upstream even if "Disable IPv6" is checked

[timkgh]

Issue Details

Disable IPv6 is checked. AAAA queries are blocked as they should, but I still see PTR queries for *.ip6.arpa sent to the upstream private DNS server.

I think these should also be blocked.

Hello. The previously-poorly-named “Disable resolving of IPv6 addresses” option only disables the resolving of AAAA queries. And I'm not sure if we want it to do more than that (@ameshkov?).

You can block all such PTR queries by a simple ||ip6.arpa custom rule.
