Finding out the Network Address of IP Address
CALCULATING NETWORK ADDRESS OF AN IP ADDRESS: In this Post I will share you a trick to find out, What is the network address of a IP address. In CCNA or JNCIA Exams we get questions like: what is network address of 172.16.12.100/29? what is network address of 192.168.100.100/26? If it's a class-full subnet (/8, /16, /24) we can find it out easily but in case of a subnetted IP address we required some more time to identify the Sub network IP address. Below is a simple 3 steps formula that gives you accurate Sub-network IP address of any given IP: Step-1: Find out how many hosts we get in that subnet: (Including Network address and Broadcast address) Like, in 192.168.1.0/24 we get 255 Hosts. 192.168.1.0/29 we get 8 Hosts. 192.168.1.0/30 we get 4 Hosts. Below is the chart that explains how many hosts per bit we get: The above Pic represents the 8 Bits in an octet, And no. of hosts per each bit. So, Clearly if we ...
