DNS means Domain Name System and is a decentralized naming system for computers, services, or other resources connected to the Internet or a private network.

DNS translates domain names to the numerical IP addresses needed for locating and identifying computer devices. DNS exists since 1985 and is one of the essential components of the world wide web.

When a user types a domain in the browser, that domain name is translated into an IP address by the DNS resolver. The DNS servers (resolvers) are in contact with the multiple authoritative nameservers, like wordpress.com, Digital Ocean and Vultr.

If the DNS resolver goes offline, users still have access to the Internet, but all the domains will not work. The browser will only work through IP addresses.

Internet Service Providers such as Zol, Econet, TelOne and Telecel normally set up their own DNS servers. As well as that, the router used in the home or office will also be used by computers attached to them as a DNS server for URL queries. Router act as gatekeepers, forwarding on requests to an ISP’s DNS servers.
