What is DNS?
DNS, abbreviation of Domain Name System is a massive database that allows you to browse and download stuff from the Internet. For an explanation, consider this:
- You type in a web address into your browser, like 'right-now-in-tech.blogspot.com'.
- The browser sends a request to your Internet Service Provider (ISP), who in turn sends the request to a DNS server.
- This server looks up your address and finds an IP address for the website you are trying to visit.
- If it doesn't have one, it sends a request to another DNS server.
- When the IP address is found, it is sent back to your ISP, and then to your computer.
- Your browser then uses that IP address to look up Right Now In Tech on the World Wide Web.
Many times, even two or more IP addresses are required to display all the content on a website. This may be in case of adverts, which are actually located on other servers, embedded videos and many more things.
