What is the IP range and subnet code of each subnet? Does anyone know how to count?
The subnet mask should be configured as: 255.255.255.224.

In this way, the 202.25.25.0 network segment is divided into 8 subnets, each subnet has 32 IP addresses, and each subnet has 30 IP addresses that can be used to assign hosts, which meets your requirements.

The following is the IP range of 8 network segments, and the first and last IP addresses of each network segment are not available.

Their subnet masks are all 255.255.255.224.

202.25.25.0~202.25.25.3 1

202.25.25.32~202.25.25.63

202.25.25.64~202.25.25.95

202.25.25.96~202.25.25. 127

202.25.25. 128~202.25.25. 159

202.25.25. 160~202.25.25. 19 1

202.25.25. 192~202.25.25.223

202.25.25.224~202.25.25.255
