            CALCULATING NETWORK ID ON FINGERTIPS This is a very simple technique which you will never find in any other sites or books, While attempting any exams we are asked to Calculate the Network id of the given IP. It's not a recommended way to use pen, book and calculations to find out the Ans. SO, Here come's a simple Formula to calculate that within seconds. *********************************************************************************************************** *As the General subnets we can do easily, But this process is very useful in calculating subnets such as   192.168.2.181/30      * *  ==> The network ID of the subnet is 192.168.2.180 we can calculate that in less than 7 seconds with this method                  * *********************************************************************************************************** Follow the steps below: 1) Identif...
