The latter case where the user is redirected to another destination would be considered DNS Spoofing, otherwise known as "DNS Poisoning". [3] DNS blocking can be applied to individual servers/IP address, or entire blocks of IP addresses for multiple reasons. Some public DNS Resolvers, like Quad9 and CleanBrowsing, offer filters as part of their ...
A public recursive name server (also called public DNS resolver) is a name server service that networked computers may use to query the Domain Name System (DNS), the decentralized Internet naming system, in place of (or in addition to) name servers operated by the local Internet service provider (ISP) to which the devices are connected.

Reverse DNS queries are used to map IP addresses to domain names. They are PTR queries for subdomains of in-addr.arpa (for IPv4 addresses) [ 3 ] and ip6.arpa (for IPv6 addresses). [ 4 ] For example, to find the domain name associated with the IP address 203.0.113.22, one would send a PTR query for 22.133.0.203.in-addr.arpa .
The 1.1.1.1 DNS service operates recursive name servers for public use at the twelve IP addresses listed below. [11] These addresses are mapped to the nearest operational server by anycast routing. [12] The DNS service is also available for Tor clients. [13] Users can set up the service by manually changing their DNS resolvers to the IP ...

DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. [1] This can be achieved by malware that overrides a computer's TCP/IP configuration to point at a rogue DNS server under the control of an attacker, or through modifying the behaviour of a trusted DNS server so that it does not comply with internet standards.
