DNS Cache (Caching name servers), is a process by which it is stored a query DNS of an application (Internet Browser, client FTP, Yahoo! Messenger, etc …). Basically, this process helps the servers that hold the domain names, to store for a period of time (determined by the server configuration) query data on the end user's computer. In this way, a higher response speed of the web server or the server that holds data about an application is obtained and a communication bridge is created between the PC and the server.
A number of applications use the DNS cache while the application is running to check update-urile, updates or even license validity.
If you are curious to see which servers have DNS caches on your PC, open (with administrator privileges) a Command Prompt (Ctrl+Win > cmd > Enter) if you typed:
ipconfig /displaydns
In order to clean DNS cache, type in CMD :
ipconfig /flushdnsIn CMD you should receive the message:
Windows IP Configuration
Successfully flushed the DNS Resolver Cache.
Enable and disable DNS cache (DNS Client service) :
net stop dnscache
net start dnscacheDNS Cache Reference (Recursive and caching name server) (Wikipedia).
