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.
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 its database. The most common types of records stored in the DNS database are for start of authority ( SOA ), IP addresses ( A and AAAA ), SMTP mail exchangers (MX), name servers (NS), pointers for reverse DNS ...
dnsmasq caches DNS records, reducing the load on upstream nameservers and improving performance, and can be configured to automatically pick up the addresses of its upstream servers. dnsmasq accepts DNS queries and either answers them from a small, local cache or forwards them to a real, recursive DNS server.
Restart your computer. Sometimes turning it off and turning it back on again is the best solution to a slow computer. When the computer restarts, all current programs and applications are closed ...
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.
A browser's cache stores temporary website files which allows the site to load faster in future sessions. This data will be recreated every time you visit the webpage, though at times it can become corrupted. Clearing the cache deletes these files and fixes problems like outdated pages, websites freezing, and pages not loading or being ...
Microsoft Windows Server operating systems can run the DNS Server service. This is a monolithic DNS server that provides many types of DNS service, including caching, Dynamic DNS update, zone transfer, and DNS notification. DNS notification implements a push mechanism for notifying a select set of secondary servers for a zone when it is updated.
Two common varieties are DNS cache poisoning [2] and ARP cache poisoning. Web cache poisoning involves the poisoning of web caches [3] (which has led to security issues in programming languages, including all Python versions at the time in 2021, and expedited security updates [4]). Attacks on other, more specific, caches also exist. [5] [6] [7]
