 Visit to learn the theory more clearly Before questions Slash Notation Three Rules in CIDR Block Question 1 Given the CIDR representation 168.1.2.10 / 18. Find the range of IP Addresses in the CIDR block. IP address - 168.1.2.10                          10101000.00000001.00000010.00001010 Number of bit allocated to Network ID      -      18 Number of bit allocated to Host ID                -       32-18 = 14 Subnet mask - 11111111.11111111.11000000.00000000 First address = (given address) AND (Subnet mask) 1 0 1 0 1 0 0 0 . 0 0 0 0 0 0 0 1 . 0 0 0 0 0 0 1 0 . 0 0 0 0 1 0 1 0 AND 1 1 1 1 1 1 1 1 . 1 1 1 1 1 1 1 1 . 1 1 0 0 0 0 0 0 . 0 0 0 0 0 0 0 0 1 0 1 0 1 0 0 0 . 0 0 0 0 0 0 0 1 . 0 0 0 0 0 0 0 0 . 0 0 0 0 0 0 0 0 1 6 8 . 1 . 0 . 0 Last Address = (any address) OR [NOT (Subnet mask)] NOT (Subnet mask) = 1 1 1 1 ...

Short Note - IP classes

IP address classes and Subnet mask An  IP address  is a unique identifier or numeric label used to identify devices connected to the network. This helps to develop a virtual connection between source and destination for packet communication in networking. As we develop the network, we consider the scale, the number of devices connected to the network, and other requirements. That IP address space is divided into 5 classes and then we can get a better idea of ​​the range we need to use when we need to build a network. Class A Class B  Class C  Class D Class E Important Dividing IP address space (2 * 32 no. of IP addresses) into 5 classes is called  Classful addressing . In this concept, the number of hosts for each class is fixed. We use the concept of  Classless Inter-Domain Routing (CIDR)  concept because of the limitations of classful addressing. Before short note IP classes are identified by the 1st octet of the IP address (left most from all)....
