Subnetting | Find Range, Network ID, Host, Broadcast address with Numerical Examples | IP address
@crescenttechnologies85 In this video, I have explained Numerical Questions to find Range, Network Id, and Host using the given IP address. Binary to Decimal: https://youtu.be/HahQ8h8KEYk?si=YXBldT-JntrKHCN1 Decimal to Binary: https://youtu.be/Lh8BshZifJE?si=7cGxZlTqGLP5ZpMt
This video will be helpful for students who are preparing for competitive exams like GATE, UGC NET, PSUs, NIC, PGT TGT as well as College/University exams. A subnet is a logical subdivision of an IP network. The process of dividing a network into two or more networks is called subnetting. In this video, I will use an example to demonstrate a simple way of subnetting.
Some essential terms used in the Video
1. Subnet- The dividing of an IP address into multiple smaller units that can work as a separate network unit known as a subnet, in the host network is known as the subnetting process.
2. Subnetting allows the network to avoid frequent traffic problems that occur in the channel, resulting in the smooth transmission of information in the network.
3. Network ID- A network ID or NetID is the fragment of IP address that classifies the network for a specified host i.e., it tells us which network the host belongs to, generally comprised of one to up to four octets in dotted-decimal representation
4. Host ID- It is the fragment of an IP address that uniquely classifies a host on a specified TCP/IP network. A host ID can be found simply by ANDing the IP address in binary form with its respective default subnet mask (in binary form). The other fragment of an IP address is the network ID, which identifies the network to which the host belongs
5. Subnet Mask- A subnet mask is a 32-bit number created by setting host bits to all 0s and setting network bits to all 1s. In this way, the subnet mask separates the IP address into the network and host addresses.
6. Host ID Range- The host range will start from the next address after the subnet address for example for the subnet 192.168. 116.32/27 the host range will start at 192.168. 116.33 and end at one less the broadcast address which will be 192.168. 116.62 since the broadcast address is 192.168.
7. Number of Usable Hosts- The network and broadcast addresses are not available to be assigned to hosts on the network. So, the number of available addresses that you can assign to hosts is the total number of addresses minus two
8. Broadcast ID- A broadcast address refers to a special IP address that is used to send a message or packet to all devices on a network. Broadcast addresses are commonly used for network management tasks, such as sending out configuration updates or discovery requests.
9. Limited broadcast address- is defined as which sends or broadcasts packets to all hosts connected to its own or home network.
