Deny ipv6 lookups

This reduces geolocation accuracy and also increases privacy since ipv4 is shared among many users.

    Looks like you're confused. IPv6 privacy is secured by privacy extensions (RFC 4941).

    Blocking v6 will only end in problems without any advantage.

      DynamicNotSlow Have a look at this https://www.internetsociety.org/tag/ipv6-security/ especially myths 2, 4, 5, 6. So ipv6 is not as private as one might assume.

      Also, ipv6 address are almost unique, and so can give more precise fingerprinting. Whereas since ipv4 are limited, they are shared and the outbound interface may be located somewhere else, thereby giving "fake" geolocation.

      These are the reasons why many VPNs still do not support ipv6.
