title: What are the effects of incorrectly setting the netmask?
body: <p>What are the effects of incorrectly setting the netmask?  I have a C++ application that sets the network mask of a device.  If the netmask is set incorrectly, tftp doesn't seem to work properly.  Why would this happen?  What other problems occur when the netmask is not properly set for a device/PC? </p>
