Well, a /22 gives you a little over 1, 000 addresses. Half will be taken by the 400 host subnet, for a /23. The 200 host subnet needs a /24 subnet, and the 2 50 host subnets will each need a /26. In addition, at least three 2 host subnets will be needed for the inter-router links (assuming a tree). So, you might start with the big pieces first, to get: 400 192.168.24.0 /23 (this uses all of 24.x and 25.x) 200 192.168.26.0 /24 (uses all of 26.x) 50 192.168.27.0 /26 (1/4 of 27.x) 50 192.168.27.64 /26 (1/4 of 27.x) Then you may want to start at the end and work backwords for the router links. This may leave a larger chunk, or so, for future use. 2 192.168.27.252 /30 2 192.168.27.248 /30 2 192.168.27.244 /30 Note: In many cases it is best to take the larger chunks out of the middle and then work outword for the smaller subnets. In this example that wasn't practical as the largest piece had to completely take up the first, or last, half of the available range.
