  2. DNS sinkhole - Wikipedia

    en.wikipedia.org/wiki/DNS_sinkhole

    One example of blocking malicious domains is to stop botnets, by interrupting the DNS names the botnet is programmed to use for coordination. [8] Another use is to block ad serving sites, either using a hosts file-based sinkhole [9] or by locally running a DNS server (e.g., using a Pi-hole). Local DNS servers effectively block ads for all ...

  3. Domain Name System - Wikipedia

    en.wikipedia.org/wiki/Domain_Name_System

    The Domain Name System maintains the domain name hierarchy and provides translation services between it and the address spaces. Internet name servers and a communication protocol implement the Domain Name System. A DNS name server is a server that stores the DNS records for a domain; a DNS name server responds with answers to queries against ...

  4. Domain name server - Wikipedia

    en.wikipedia.org/wiki/Name_server

    Below the root, Internet resources are organized into a hierarchy of domains, administered by the respective registrars and domain name holders. A DNS name server is a server that stores the DNS records, such as address (A, AAAA) records, name server (NS) records, and mail exchanger (MX) records for a domain name (see also List of DNS record ...

  5. DNS hijacking - Wikipedia

    en.wikipedia.org/wiki/DNS_hijacking

    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.

  6. Network domain - Wikipedia

    en.wikipedia.org/wiki/Network_domain

    A domain controller is a server that automates the logins, user groups, and architecture of a domain, rather than manually coding this information on each host in the domain. It is common practice, but not required, to have the domain controller act as a DNS server. [4] That is, it would assign names to hosts in the network based on their IP ...

  7. Root name server - Wikipedia

    en.wikipedia.org/wiki/Root_name_server

    A root name server is a name server for the root zone of the Domain Name System (DNS) of the Internet. It directly answers requests for records in the root zone and answers other requests by returning a list of the authoritative name servers for the appropriate top-level domain (TLD).

  8. Blackhole server - Wikipedia

    en.wikipedia.org/wiki/Blackhole_server

    The AS112 project is a group of volunteer name server operators joined in an autonomous system. They run anycasted instances of the name servers that answer reverse DNS lookups for private network and link-local addresses sent to the public Internet. These queries are ambiguous by their nature, and cannot be answered correctly.

  9. DNS spoofing - Wikipedia

    en.wikipedia.org/wiki/DNS_spoofing

    A Domain Name System server translates a human-readable domain name (such as example.com) into a numerical IP address that is used to route communications between nodes. [1] Normally if the server does not know a requested translation it will ask another server, and the process continues recursively. To increase performance, a server will ...
