I'm working for a small company where i want to create some subnets, 1 subnet for the servers, 1 for main office and 2 subnets for other offices
This is what i had in mind:
192.168.1.0 = server subnet (10 servers)
192.168.2.0 = main office (30 workplaces)
192.168.3.0 = other office (10 workplaces)
192.168.4.0 = other office (10 workplaces)
Now is the question what subnetmask i need to use... most simple should be 255.255.0.0 but i'm affraid i will get bad performance because broadcasts and so.
Please advice, i'm a beginner in subnetting.
