=====================
1. Open Website in Browser like Chrome, Mozilla etc.
=====================
2. Next step is we want IP address details, which is mapped with the Website
=====================
3. Browser Cache is checked, details will be present if website is visited recently on this browser
=====================
4. Computer Cache is checked, details will be present if website is visited recently on this computer
=====================
5. Recursive DNS is checked, Recursive DNS is simply the Default DNS fed to our computers by the ISP. Details will be present if some other customer connected to this ISP have accessed the same website using same Default DNS.
=====================
6. Request goes to Root DNS. Root DNS do not maintain the mapping details.
=====================
7. Root DNS simply checks the extension details like “.com”
=====================
8. Then Root DNS sends Request to Name Server, which is responsible for “.com” TLD
=====================
9. Then .com Name Server tells where to find Authoritative Name Server
=====================
10. On Authoritative Name Server, A record will be present
=====================
11. A record contains Website to IP mapping details
=====================
12. This details will now be saved in cache for next time quicker DNS resolution
=====================
