What is DNS?

DNS (Domain Name System), is the service which translates between Internet names and Internet addresses. Internet names are the names which we use to refer to hosts on the Internet, such as www.allaboutmypc.com, www.directoryparking.com, and www.whatismyfee.com. Internet addresses are the numbers which routers use to move traffic across the Internet, such as 75.127.282.92.


Why do I need to flush DNS cahce?

Most DNS clients cache the results of name resolution requests. This speeds up name resolution if multiple lookups are done to the same address, such as is common when browsing the web. Sometimes a bad DNS entry will be cached and you will need to either flush the DNS cache to get rid of it, or wait up to 24 hours for it to be dropped from the cache automatically.


How to Flush DNS in Microsoft Windows

In Microsoft Windows, you can use the command ipconfig /flushdns to flush the DNS resolver cache. You can also use the command ipconfig /displaydns to view the DNS resolver cache.
