The following is a CIDR Subnetting question.

What are the subnet mask, first available host address of subnet ONE (NOT SUBNET ZERO), and the maximum number of hosts per subnet for the following networks below? (You need to allow for the maximum number of hosts).

1. Network ID: 188.129.0.0 - Subnets Required: 41

2. Network ID: 137.72.0.0 - Subnets Required: 84

3. Network ID: 221.99.189.0 - Subnets Required: 30

Please provide a detailed and complete answer for this question. Do NOT give me definitions of what a subnet mask is or what a network id is, or whatever. I need 100% complete/genuine help and a definitive solution to my problem.
