Re: Clear DNS Cache & Register Error Reporting
Many Internet connectivity issues are due to the corrupted DNS cache on a computer. This article explains the term DNS Cache and teaches you how to clear and renew it on a Windows computer.
What is DNS Cache?
Before explaining the term DNS Cache, you must understand DNS Server. DNS Server acts between your computer and the server on the Internet.
Let me explain it.
When you type www.SysToSys.com on the browser address bar, your computer does not understand the name of this blog.
Your computer understands only the IP address. So, it requests the DNS server to translate the domain name SysToSys.com and find the destination IP address.
Once your computer learns the IP address of the website www.SysToSys.com, it will save the information in the DNS Cache.
So, your computer does not want to contact the DNS Server the next time when you type www.SysToSys.com on the browser.
Now, you understand the term DNS Cache.
