How does subnet masks reduced network congestion & increase network performance.?
Subnet masks break down your IP network into smaller “sub networks.” By having several smaller subnetworks instead of one large network, the traffic congestion on each smaller network is lower plus the broadcast packets sent from your computers and devices only stay within the individual subnetworks. Broadcast packets are packets of information sent out from a computer or device which is destined for all devices on the network; mainly intended to gather information or to identify a specific computer, device, or service. These broadcast packets can really jam up a really large network. Subnetting these larger networks keep the broadcasts within each smaller network. Let’s say we have one really large network with 200 users and 10 servers. This is a total of 210 IP devices (not including the switches and other network infrastructure which have IP addresses). If all of these clients and servers were on the same network (let’s say a 192.168.1.0/24 network for example, which would have a su
