DNS hijacking, DNS poisoning, or DNS redirection is the practice of subverting the resolution of Domain Name System (DNS) queries. 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.
DNS spoofing, also referred to as DNS cache poisoning, is a form of computer security hacking in which corrupt Domain Name System data is introduced into the DNS resolver 's cache, causing the name server to return an incorrect result record, e.g. an IP address. This results in traffic being diverted to any computer that the attacker chooses.

If a user mistypes the name of a website then the ...

It associates various information with domain names (identification strings) assigned to each of the associated entities.
IP hijacking is sometimes used by malicious users to obtain IP addresses for use in spamming or a distributed denial-of-service (DDoS) attack. When a router promulgates flawed BGP routing information, whether that action is intentional or accidental, it is defined by the Internet Engineering Task Force (IETF) in RFC 7908 as a "route leak".
Google Public DNS. Google Public DNS is a Domain Name System (DNS) service offered to Internet users worldwide by Google. It functions as a recursive name server . Google Public DNS was announced on December 3, 2009, [1] in an effort described as "making the web faster and more secure." [2] [3] As of 2018, it is the largest public DNS service ...
