Computer network classification

What criteria can you use to classify computer networks

There are actually 5 classes of IP addresses; A through E. They are classified based on the number of hosts needed. For instance Class A adresses are reserved for large corporations because there are 16 million possible host addresses in the network. However, there are only 127 Class A addresses. Certain other IP address ranges are reserved for instance 127.0.0.1 is a loopback address.

IP addresses can also be classified as public/private. Your home network will have a couple of private addresses (192.168.0.xxx) and one public ip address to be used on the internet.

And if that wasnt enough ways to classify addresses. They can also be classified static/dynamic. If an address is static it is assigned to a MAC address/device and doesn't change. These addresses usually cost extra from your ISP. If your address is dynamic it changes at a set interval usually somewhere around 2 weeks.

Hope this helps!
