DNS resource records are primarily a massive collection of IP addresses of domain names, services, zones, private networks and devices used by DNS servers to locate services or devices on the Internet worldwide, and are inherent to the functionality of the Internet. DNS servers then translate the numerical IP addresses from the DNS resource records into user-friendly alphabetic names that humans can easily remember.Continue Reading
The common metaphor used by experts to describe this protocol is that it's the phone book of the Internet. Internet devices generally use numeric IP addresses to communicate with each other. Without a Domain Name System record, people need to remember and type the numerical IP addresses of websites or devices into their Internet browsers to access a service or device. DNS servers are responsible for mapping domain names and assigning numerical IP addresses, and they update the resource records several times in a day.
There are several types of DNS resource records, and each serves a different function. Each record type is categorically assigned to a specific DNS server that's also categorically assigned by the Domain Name System a specific class of service. The protocol is designed in this way to avoid DNS server-request congestion that can slow down Internet traffic.Learn more about Internet & Networking
A DNS, or domain name system, server error occurs when the client, or Web browser, cannot communicate with the DNS server either because there is an issue with DNS routing to the domain or the server is down. The DNS server is responsible for converting the website URL, or uniform resource locator, into an IP address that is required for actual communication. DNS errors are the most common errors received by users while browsing the Web.Full Answer >
Flushing the DNS cache causes the computer to erase stored IP addresses and query servers for new information. The DNS cache allows computers to keep pages updated and synchronized with each other. Clearing the DNS cache becomes necessary when a large number of HTML 404 error codes appear or the cache is poisoned due to a virus or glitch.Full Answer >
DNS, which stands for "Domain Name System," works like a phone book that converts a domain name or website name into an Internet protocol (IP) address, a unique number that identifies every device on a network. DNS enables users to look up a website or send an email through a memorable name, instead of having to remember and type in its IP address.Full Answer >
