What are the 3 major classes of an IP network?

What does IP not in subnet range?
Answered December 25, 2019. In general terms, this means a certain IP address doesn’t belong to the block of IP’s defined by the subnet mask for an arbitrary subnet. As an example: subnet 1: 192.168.1.0 /25. subnet 2: 192.168.1.64 /25.
