Classes and Hosting of IP addresses.
Hi Sarah,
An IP address class is determined based on the decimal values of their first octets. An IP address can start with a decimal value between 1 and 255.
Â
Below is the list of the 5 different classes of IP address;
Â
Class A: 1.0.0.0 to 127.255.255.255.255Â
Â
Class B: 128.0.0.0 to 191.255.255.255
Â
Class C: 192.0.0.0 to 223.255.255.255
Â
Class D: 224.0.0.0 to 239.255.255.255
Â
Class E: 240.0.0.0 to 255.255.255.255
Â
Remember that you can determine which IP address belongs to a particular class by looking on the first octet of the IP address.
Â
Class A, B, and C are used to identify workstations, routers, switches, and other devices. Class D and E are reserved IP addresses for special use.Â
Â
Below is the list of the number of hosts that supports in every class:
Â
Class A IP address class consists of 16, 277, 214 number of host IDs per network ID.
Â
Class B IP address class consists of 65, 534 number of host IDs per network ID.
Â
Class C IP address class consists of 254 number of host IDs per network ID.
Â
Class D IP addresses are reserved for multi cast groups.
Â
Class E IP addresses are reserved for future use, or Research and Development Purposes.

I hope this will answer your questions.
