answer those....and we can take it to the next step.
An ipconfig /release..../renew is only going to get you a new dynamic address from a local dhcp request. You would need to renew from your edge device, thats IF your ISP or whatever you answered in question 1 is providing dynamic IP.
An arp request (arp -a) is only going to show you a MAC to IP mapping, or vice versa.
