There are loads of reasons in favor of subnetting, including the following benefits:
Reduced Network Traffic We all appreciate less traffic of any kind. With networks, it’s no
different. Without trusty routers, packet traffic could grind the entire network down to a
near standstill. With routers, most traffic will stay on the local network; only packets destined
for other networks will pass through the router. Routers create broadcast domains.
The more broadcast domains you create, the smaller the broadcast domains and the less
network traffic on each network segment.
Optimized Network Performance This is the very cool reward you get when you reduce
network traffic!
Simplified Management It’s easier to identify and isolate network problems in a group of
smaller connected networks than within one gigantic network.
Facilitated Spanning of Large Geographical Distances Because WAN links are considerably
slower and more expensive than LAN links, a single large network that spans long
distances can create problems in every area previously listed. Connecting multiple smaller
networks makes the system more efficient.
