Aug 30, 2014 · DNS: Stands for "Domain Name System." Domain names serve as memorizable names for websites and other services on the Internet. However, computers access Internet devices by their IP addresses. DNS translates domain names into IP addresses , allowing you to access an Internet location by its domain name.
Root Server: A root server is part of the supporting infrastructure of the Internet, and facilitates Internet use by acting as the backbone of online access. Root servers are an essential part of the domain name system (DNS). They publish root zone file contents, which are responsible for DNS functionality, to the Internet. DNS associates DNS Zone File: A Domain Name System zone file (DNS zone file) is a simple text file which is automatically bundled with DNS records. The file contains all the necessary information of all resources records for the particular domain. Alternatively, it can also contain the complete Internet Protocol to domain mapping of the domain. DNS zone DNS (Domain Name Server) resolution is the process of translating IP addresses to domain names. When a profile is configured to look up all numeric IP addresses, Webtrends makes a call to the network's DNS server to resolve DNS entries. Each computer has its own IP address. The Domain Name System (or DNS) converts human readable domain names (like: www.google.com) into Internet Protocol (IP) addresses (like: 173.194.39.78). Computers can only communicate using series of numbers, so DNS was developed as a sort of “phone book” that translates the domain you enter in your browser into a computer readable IP.

Common reasons for using split DNS systems is to hide internal information from external clients on the Internet or to allow internal networks to resolve DNS on the Internet.
DNS amplification attack: A DNS amplification attack is a reflection-based distributed denial of service ( DDos ) attack.
A DNS query (also known as a DNS request) is a demand for information sent from a user's computer (DNS client) to a DNS server. In most cases a DNS request is sent, to ask for the IP address associated with a domain name. An attempt to reach a domain, is actually a DNS client querying the DNS servers to get the IP address, related to that domain. May 01, 2020 · A DNS cache (sometimes called a DNS resolver cache) is a temporary database, maintained by a computer's operating system, that contains records of all the recent visits and attempted visits to websites and other internet domains. Oct 04, 2018 · Once the DNS server finds the domain-to-IP translation, it will cache it so that upon subsequent requests for that domain, the DNS lookup will happen much faster. However, this is where DNS spoofing can become a real problem since a false DNS lookup can be injected into the DNS server's cache thus altering the visitors' destination. The overreaching definitions of the two principal name spaces in the Internet, the Internet Protocol address (IP address) space and the Domain Name System (DNS), are directed by a maintainer organization, the Internet Corporation for Assigned Names and Numbers (ICANN).
A name server is a computer application that implements a network service for providing responses to queries against a directory service. It translates an often humanly meaningful, text-based identifier to a system-internal, often numeric identification or addressing component. This service is performed by the server in response to a service protocol request. An example of a name server is the server component of the Domain Name System, one of the two principal namespaces of the Internet. The mo
