two machines cannot &quot;talk&quot; to each other unless they are on the same subnet range... OR you have some sort of routing between the subnets.<br />

Thank you, that is what my understanding is, but When I static my subnet to 128 I can talk and ping all addresses in my network of 200 computers that are mixed with 128 and 255 as their subnet; but when I static my address to 255, I can talk and ping all 255 but no 128 address.

This might be simple but I am wondering, if I have one network at 255.255.255.0 and another at 255.255.128.0 I can talk to the 255.255.255.0 network if I am at the 128 network but not backwards without a router. Why is this? If I am at 255.255.128 can I talk to all the other network addresses above mine but not below?

Networking is the process of connecting computing devices, peripherals and terminals together through a system that uses wiring, cabling or radio waves that enable their users to communicate, share information and interact over distances. Often associated are issues regarding operating systems, hardware and equipment, cloud and virtual networking, protocols, architecture, storage and management.
