DNS Caching at a glance
Apr 14th
What is DNS Caching?! DNS caching is a mechanism that enables a client or a server DNS resolutions queries to be saved locally for a set timeframe on that DNS server or client. A DNS query is a request for name resolution that is sent to a DNS server to resolve a name-to-IP-address.
Since Caching stores the information obtained through a previous query locally it improves DNS performance and substantially reduce DNS related traffic on the network. It eliminates the need for repetitive queries to the remote DNS server.
The period of time or TTL (Time to Live) of which the DNS cached query may be stored in the DNS cache, either on the client side or on the server side, is determined by the authoritative server of that resource record. This value applies to all cached DNS resource records and it will be removed once expired regardless if the same record entry accessed before the TTL expires. (more…)

Yet in Windows environment most administrators prefer the GUI method to get the job done. However, Windows can be administrated through command line as well; Windows server 2008 Server Core supports strong command line management capabilities. (more…)
