The Importance of DNS Servers
Greetings! If you’re someone who loves to surf the internet, or wants to establish a website, then you should know the importance of Domain Name System (DNS) servers. Simply put, DNS is the address book for the internet. It translates domain names like www.example.com into IP addresses that computers can understand. Without DNS, we would have to remember long strings of numbers to access any website, which is not practical or user-friendly.
