What is DNS?
DNS is an address book for the internet where the digital "home" address is shown for each site. For example, yandex.com "lives" at the address 220.127.116.11.
Each time you go to a webpage, the browser looks for its address in the DNS system. The faster the nearest DNS server to you works, the faster the site opens.
