I have base ip address 10.6.0.0/8 This is A class ip address. I need to divide this network into 12 subnets, and I need at least 80 computers in one network. Please explain how to calculate correctly subnets. I understand that subnets count should be power of two, so the nearest is 16. But I don't understand what should I do next. Please explain. I have spent day trying to understand this.Thanks.
