CA 16 - IP address and Subnet

IP ADDRESS IP (Internet protocol) address is a unique identifier for each device connected in network. It is assigned uniquely for each device. Types of IP Address IPV4 This is the most commonly used type. For example, the format looks like 10.1.34.81 It has 32-bits which is divided into 4 octet, 8 bits each. The range of each octet will be 0-255. 2.IPV6 Not commonly used but ready for future. It uses hexadecimal number system. It has 128-bits. For example, the format looks like 2001:0db8:85a3::8a2e:0370:7334. Parts of IP Address IP Address has 2 parts namely Network and Host part. Network part: defines the network Host part: defined the device in network SUBNETS Subnets is smaller and manageable division of larger network. Subnets exists in order to decrease the network congestion, increase security and organise network efficiently. Subnet Mask A subnet mask decides which part of IP is Network and Host. Here, First 3 octets = Network part Last octet = Host part CIDR Notation It is mod
