The Internet’s DNS system works much like a phone book by managing the mapping between names and numbers. DNS servers translate requests for names into IP addresses, controlling which server an end user will reach when they type a domain name into their web browser.
What is DNS and how it benefits Internet?
DNS translates domain names to IP addresses so browsers can load Internet resources. Each device connected to the Internet has a unique IP address which other machines use to find the device. DNS servers eliminate the need for humans to memorize IP addresses such as 192.168.

What is the benefit of changing DNS?
An alternate DNS server has multiple purported benefits including: Faster servers compared to the ISP server so requests get processed faster and more smoothly. More reliable servers with better uptime. Geographically closer servers for a closer connection and therefore faster speeds.

What is one advantage of using DNS instead of hosts files?
For example, unlike a hosts file on each machine, a DNS server works across multiple machines within a LAN. A DNS server also supports more flexible file formats that can block an entire domain, not individual hostnames as one must with a hosts file.
What is better DNS or https?

What are the problems with DNS?
