Mar 13, 2017 at 19:42 comment added nd510 @RyanKelso Okay sure you have 169 address but that does not apply to his question because this random ip address generated by the computer, not the network, is NOT going to be used to identify you so its completely irrelevant to what he is asking and is only specific to Windows. If you feel the 169 is so relevant to his question, then answer the question yourself.
Mar 13, 2017 at 19:29 comment added Ryan Kelso @ncd275 If you're not connected to a network at all, of course your computer can't find a DHCP server because it's not connected to anything, resulting in a 169.254.*.* IP for your computer. If you then connect to a network (i.e. a WiFi hotspot), and it has DHCP, you will be given a new IP from that DHCP server. At no point do you have no IP in Windows AFAIK. If you mean that you have no PUBLIC IP Address before connecting to their network, then that's true, but you should clarify that in your answer.

Mar 13, 2017 at 18:52 comment added Mr. E @ncd275 I saw that in tp-link usb adapters (I think it was the wn722n) and on some pci ethernet cards (Can't remember the vendor)
Mar 13, 2017 at 18:50 comment added nd510 @Mr.E interesting, usually vendors are assigned an EUI identifier but never heard of the same mac being used. Do you remember what kind of devices they were selling?
Mar 13, 2017 at 18:48 comment added nd510 @RyanKelso that's when your computer can't find a DHCP server and doesn't really apply here. The wifi hotspot is going to act as a DHCP and if your computer is assigned the 169..... address that means it can't get a IP address from the hotspot and therefore is not going to be connected to that network.
Mar 13, 2017 at 17:42 comment added Ryan Kelso In Windows, you automatically are still given an IP Address when not connected to a network. techrepublic.com/forums/discussions/…
Mar 13, 2017 at 15:49 comment added Mr. E MAC addresses SHOULD be unique per device, but I have seen some vendors selling multiple devices with the same MAC address
