10.23.2.0/255.255.255.0 in Classless Inter-Domain Routing is represented as: 10.23.2.0/24 where 10.23.2.0 is the subnet address whereas 24 is the no of ones in the mask i.e. 255.255.255.0 as it includes 24 1's. Hence using this notation we can include both subnet prefix as well as subnet masks.
Classless Inter-Domain Routing (CIDR) notation is a way to represent IP addresses and their subnets more compactly. It simplifies the representation of subnets by combining the subnet address with the number of significant bits in the subnet mask.
For example, instead of expressing a subnet as 10.23.2.0/255.255.255.0, CIDR notation condenses it to 10.23.2.0/24. Here, 24 indicates the number of bits set to 1 in the subnet mask (255.255.255.0). CIDR notation provides a concise and efficient means to convey both the subnet address and mask details.
