When your ISP configures your internet connection, it is set to use the ISP's default DNS. But the IP address for each site is a long string of numbers, and unless you are a mnemonist, you cannot remember the IP address for every site you want to and need to visit.
The DNS server helps route the request to the appropriate IP address of that website.Įach website has an IP address. When you enter the name of a website in your browser address bar, your browser sends that name to a DNS server. The Domain Name System translates a human-readable website name to an IP address.
