Existing network along/16, the existing 6 departments, 1 department needs 400 IP addresses, the second department needs 150 IP addresses, third department needs 600 IP addresses, the fourth department needs 200 IP addresses, the fifth department needs 700 IP addresses, sixth department needs 500 IP addresses, please use variable-length subnet mask subnetting schemes are given (subnets, subnet mask, the IP address of the first available, the IP address of the last one available and the broadcast address of each subnet),
How to measure?

Start with the desired host more department division:
5 departments: subnet number: along/22, available IP address range: 172.16.0.1/22-172.16.3.254/22, the broadcast address: 172.16.3.255/22
Third sector: a subnet number: 172.16.4.0/22, available IP address range: 172.16.4.1/22-172.16.7.254/22, the broadcast address: 172.16.7.255/22
6 departments: subnet number: 172.16.8.0/23, available IP address range: 23-172.16.9.254 172.16.8.1//23, the broadcast address: 172.16.9.255/23
Department: 1 subnet number: 172.16.12.0/23, available IP address range: 23-172.16.13.254 172.16.12.1//23, the broadcast address: 172.16.13.255/23
Fourth division: the subnet number: 172.16.16.0/24, available IP address range: 172.16.16.1/24-172.16.16.254/24, the broadcast address: 172.16.16.255/24
The second sector: a subnet number: 172.16.20.0/24, available IP address range: 172.16.20.1/24-172.16.20.254/24, the broadcast address: 172.16.20.255/24

A department has more than 600 IP addresses, if in a subnet is not divided into science, if it is a problem to practice, to further understand the variable-length subnet, if is the actual project, advice on these IP needs more department can be divided into subnets again, keep the following in 255,

Have what not science, one of our direct the development of the private cloud mask is 22,,,,
