What is subnetting in IP address?
A subnetwork or subnet is a logical subdivision of an IP network. The practice of dividing a network into two or more networks is called subnetting. This results in the logical division of an IP address into two fields: the network number or routing prefix and the rest field or host identifier.
Why do we need subnetting in IP addressing?
Why is subnetting necessary? Because an IP address is limited to indicating the network and the device address, IP addresses cannot be used to indicate which subnet an IP packet should go to. Routers within a network use something called a subnet mask to sort data into subnetworks.
What is subnetting what are its advantages and disadvantages?
Hence, it increases Time complexity. In the case of Subnet, more time is required for communication or data transfer. In the case of Single Network only two IP addresses are wasted to represent Network Id and Broadcast address but in case of Subnetting two IP addresses are wasted for each Subnet.
What is the advantage of subnetting an IP address?
Advantages of using subnetting: It is useful to control and to reduce the network traffic by limiting number of broadcasts. It is allowed any organization to subnet its network without needed to have a new network IP through an internet service provider (ISP).
How many IP addresses in a subnet?
Every subnet (connected through a gateway) needs at least 3 addresses: network, broadcast, gateway. subnet with 10 hosts: 4 bit host part (28 bit mask length) => 16 IP addresses – 3 – 10 – 1 (for the switch) = 2 free addresses will rest.
Where to find subnet address?
On PC, you can Find your IP address by typing “ipconfig” into the command prompt. Your IP address is next to IPv4 address, and you can find the subnet address right below it in the command prompt. On Mac, you can find your IP address and subnet address in the Network app in System Preferences.
What is the subnet portion of an IP address?
A subnet number is a specific part of a subnet address in an IP address that identifies one among several subnets as the recipient or originator of a data packet. The subnet number helps browsers to accurately use the Internet to deliver messages to specific parts of a party’s full network.
