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.
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.
Domain Name System blocking, or DNS blocking / filtering, is a strategy for making it difficult for users to locate specific domains or websites on the Internet. It was first introduced in 1997 as a means to block spam email from known malicious IP addresses .
DNS is the layer at which botnets control drones. In 2006, OpenDNS began offering a free service to prevent users from entering website spoofing sites. Essentially, OpenDNS has gathered a large database from various anti-phishing and anti-botnet organizations as well as its own data to compile a list of known website spoofing offenders.
DNS rebinding is a method of manipulating resolution of domain names that is commonly used as a form of computer attack. In this attack, a malicious web page causes visitors to run a client-side script that attacks machines elsewhere on the network.
Domain Name System (DNS) resolution is the process of translating a human-readable domain name (for example, en.wikipedia.org) into an IP address that computers can use. Every ISP runs a DNS server to allow their customers to translate domain names into IP addresses that computers understand and use.

A common method is to direct all World Wide Web traffic to a web server, which returns an HTTP redirect to a captive portal. [8] When a modern, Internet-enabled device first connects to a network, it sends out an HTTP request to a detection URL predefined by its vendor and expects an HTTP status code 200 OK or 204 No Content.
