I need test data for a IP Subnet calculator I have developed. I have tested some obvious scenarios, and all seems good, but the person developing can often be the wrong person to test.

The calculator can do one of two things:

1 - given an existing network and CIDR(mask), and a new CIDR it will create a number of networks with the appropriate number of hosts.

2 - given an existing network and CIDR(mask), and a list of c,h, (c = count, h=number of hosts) it will create the networks.

So if you have a subnet problem you think would be good to check, please post here. I'll post the results.

Thanks in advance!
