Whenever you visit a website in a browser, it is pointed to a DNS server which resolves the domain name to its IP address. The browser is then able to open the website address. The IP addresses of all the websites you open are recorded in your local system’s cache called DNS resolver cache. With time this cache piles up and often cause TCP/IP configuration errors and in case the IP address of a website changes, the browser will pick up the old IP address from the local cache and result in website opening errors.
If you want, you can also view all the DNS cache records. To do so, open the command prompt and type the command “ ipconfig /displaydns”.
