What is DNS?

Today, I’d like to share how to cambiare DNS on iPhone or iPad. And let’s learn what DNS is first.

DNS stands for Domain Name System. It is a system that translates domain names into IP addresses. Every device connecting to the internet is assigned a unique IP address, a string of numbers that identifies the device’s location on the internet. However, IP addresses can be difficult for humans to remember and use. That’s where DNS comes in.

DNS works like a phone book for the internet. When you type a domain name into your web browser, such as “google.com,” your device requests a DNS server to translate that domain name into an IP address. The DNS server looks up the IP address associated with that domain name and sends it back to your device. Your device then uses that IP address to connect to your requested website.

DNS is a critical component of the internet infrastructure. It allows users to access websites and other online resources using easy-to-remember domain names rather than having to remember long strings of numbers. DNS also helps improve internet connections’ speed and efficiency, allowing devices to quickly and easily locate the resources they need on the internet.

Sometimes you need to change your DNS to make smooth network on iOS, but you don’t know how to do it. Follow this detailed guide to get it.

Please connect WIFI and then perform the following steps.
