IPCONFIG /ALL shows the network resources on YOUR computer.

Next step, while in CMD.EXE:

arp -a

shows all IP addresses of things you are connected to. NETWORK resources.

arp -a and see what other IP addresses you can find. Ping everything. Sometimes my network devices don't show up. I ping them; get one bad ping and three good ones. Then they work fine. No idea why.

If you see a lot of weird stuff - 169.XXX, 224.XXX - that's just stuff for the transition to IPV6. Nothing to worry about.
