Router and Mac Address- can I make my MAC address correspond to an exact IP?
So I found out something interesting when I changed the mac address on my router the other day. I changed the mac so I could get a new ip addy. Worked great. Then after I created a new ebay/pp account and setup everything after deleting cookies and all that good stuff, I changed the mac addy back. Come to find out, I got the old ip addy back! So I got to log into my older ebay account with the same ip addy Anyone else have this work before? I use a netgear router btw...
This is absolutely normal. Your provider uses the mac address to identify you. Usually you keep the IP address for a few days even if you turn off the modem and router completely. If you change the mac address of your hardware, the server of your provider thinks it's a new one. When you switch back to your original mac address it looks like you had turned off your router for a while. Now you're back and you get the same IP address you were using earlier.
Don't get too attached to your IP addresses though, they do expire. I believe you can go to command prompt and type in ipconfig to view when your IP address expires.
It's called expiring IP addresses, they do expire which I pointed out. And after an IP address EXPIRES guess what? You can't go back to that one, and you'll be forced onto another IP address. But yes with Most routers you can do this and it will change your IP address based on that Mac Address. You may need software to get you spoofing on Modee instead of just the router software.
I think the idea is not to get the old IP address back, but to get at least a new one which hasn't been used before on one of your accounts.
Personally, I have one computer set up to connect only to my main account (that's te one I also access from my iPhone) and my notebook only connects to a neighbors router (which is wiiiddde open ) It makes it a lot easier working with two accounts at a time.
I just deleted my MAC address from my Macintosh...I didnt know it was possible.
Go to System Preferences, Network, TCP/IP, on the bottom you see your MAC address.
There is a button that says Configure IPv6. On the windows that comes out you just set it to OFF.
IPv6 is just an internet layer protocol. I don't see how turning it off could add protection. The reason why you are able to turn it off is because some routers or other hardware don't support this protocol yet.
