An IP Class Checker is a digital tool that identifies the class of an IPv4 address. In the older IP addressing scheme, IP addresses were divided into five classes: A, B, C, D, and E. Each class had a specific range of IP addresses and was used for different purposes.
While the class-based IP addressing scheme is largely obsolete, understanding IP classes can still be helpful for network administrators and security professionals. It can provide insights into the historical context of IP addressing and can be useful for troubleshooting legacy networks.
