    It depends, are you connected directly to your cable modem, or are do you have a router? If you have a router or a modem/router combination, using the renew command will only request a new IP from your router (assuming you have one and are using automatic DNS). The router will assign the first available IP address. For example, if your were on, it will probably reassign the same IP address.

    Modem/router combo. How do I get around this problem? I'm reading about dhcp but it's starting to confuse me. I've tried so many things in adapter settings.

    You can tell the router to request a new IP address. You would need to consult the documentation for the method. But in most cases your ISP's DHCP server would simply return the same IP address as before. In this regard all your ISP is obligated to do is supply you with a valid IP address. How they do this is entirely up to them.

    You can force the release/renew from your ISP, but not through the ipconfig command. That will only address the router side of your router/modem setup.

    It really depends on your ISP. Just search for the instructions for your ISP.

    Here's what I got when I searched for 'get new ip address comcast'. Of course, it came back with links related to Comcast and here is the one that talks about the router/modem combo.

    Get New IP Address With Router Comcast Modem Reset Force IP Change | According to Jim

    Basically, you have to log into your router/modem and use the utilities in there. But be careful you can screw up the settings and you might have to hard reset to get connectivity back.

    The article is complex and old, but you can get the idea. Find the right article for your ISP.
