In the IPv4 IP address space, there are five classes: A, B, C, D and E. Each class has a specific range of IP addresses (and ultimately dictates the number of devices you can have on your network). Primarily, class A, B, and C are used by the majority of devices on the Internet.

Jan 14, 2025 · Classful IP addressing, an outdated method used from 1981 to 1993, organized IP addresses into five classes (A, B, C, D, and E) based on network size but was replaced by Classless Inter-Domain Routing (CIDR) due to its limitations in flexibility and efficient address space utilization.
