What is a subnet simple?
A subnet, or subnetwork, is a segmented piece of a larger network. More specifically, subnets are a logical partition of an IP network into multiple, smaller network segments. One goal of a subnet is to split a large network into a grouping of smaller, interconnected networks to help minimize traffic.
Why should I learn subnetting?
Subnetting adds order and increased performance by splitting up traffic in larger networks. When you subnet your network, you ensure that traffic destined for a particular device within that subnet stays within the subnet. This will minimize congestion in other parts of the network.
What is the magic number in subnetting?
To find the magic number, simply subtract the number 256 from the interesting octet in the mask. Next you need to take the magic number and find the multiples of this number that is closest to or less than the interesting octet in the IP address.
What decides the subnet mask?
Subnet masks are determined by administrators. A device will either receive them through DHCP or it will be configured manually.
What is the lowest subnet mask?
For this reason, the most common smallest subnet is 8 bits, or precisely a single octet, although it can be smaller or slightly larger.
How to make a subnet?
Determine the classful mask. 192 = Class C Class C default mask = 255.255.255.0
How do you calculate the subnet mask?
How to calculate hosts or subnets based on the subnet mask. A quicker way to figure out how many hosts will exist on a particular subnet is to use the formula 2n-2, where n is the number of bits available to the host ID, where 2n represents 2 raised to the nth power.
What is a subnet table?
The Subnet table is a supporting table. Each record represents one subnet defined in network configuration setting.
