Why do larger networks tend to have 1 number network IDs while smaller networks have 3 number network IDs
The lower the amount of numbers in the ID, the more individual IDs for computers on the network Ex/ a three number network ID can have about 255 computers while a 1 number network ID can have millions of users
What is a network ID
