Question: When business requirements ask for tcp/ip exp, what EXACTLY do they mean. It doesnt take a brain surgeon to config tcp/ip in winstuff an linux. How much tcp/ip.
There's much much more to TCP/IP experience to just knowing how to configure addresses. You should know how it works and how to troubleshoot. The actual protocol suite as a whole is quite complex.
There are quite a few tutorials on TCP/IP online if you search for it on google.com. That may help you better understand what it is all about. But, for the most part, the company you are applying for probably doesn't need you to know anything beyond its stack and how to install a windows box on its network with it.
