Enhancement: Duplicate "Block IPv6" functionality (AAAA) for Type 65 (HTTPS) queries #34

Open TimErgb opened 3 years ago

TimErgb commented 3 years ago

A new "Advanced option" (default: Off) to immediately respond to Type 65 (HTTPS) queries.

As of iOS 14 a "HTTPS query will be made alongside A/AAAA queries for all connections that use Network.framework/NSURLSession for URL schemes http:// and https://, or TCP port 80 or port 443".

Compared with <=iOS13 - iOS14 increases the amount of DNS queries being sent over the wire. Optional AAAA + Type 65 blocking would dramatically reduce this traffic.
