ConstantProblems asked 3 years ago


I know you guys are probably tired of seeing these threads and for that I'm sorry.

But I've tried all of the methods on whatismyip and they haven't worked.

My ISP is Time Warner Cable Road Runner and they claim I have a dynamic IP address but it's always the same whenever I check it on this site.

I've come to learn the IP I am seeing on whatismyip is an IP that is on my router. However I tried the router method on whatismyip and that didn't work either. I still have the same IP address.

I really don't know what to do here. I know about MAC cloning but is that really safe? I honestly don't know plus I don't know how to do it. I have a Netgear router.

I would really appreciate any help you guys could give me for this.

Thank you.

Thanks for your question ConstantProblems.

On all Cable ISP's that I have worked with in the US, changing the MAC address of the first device connected to the Cable Modem will generate a fresh IP address. The first device connected to the Cable Modem should be your Router but some VoIP boxes such as Vonage and Packet8 ask you to place them between the Modem and the Router which makes them the first device connected to the Modem. The VoIP boxes will work when placed on the LAN side of the Router.

Cloning the MAC address of one of your computers to the WAN port of the Router is safe. They are MAC addresses that you already have so they will not create any conflicts. You can discover the MAC of your computers by typing "ipconfig /all" at the command prompt. The MAC address will be displayed as the Physical Address and will be 6 sets of 2 characters.

Most Routers have the ability to clone the WAN port MAC address. Simply enter the MAC from one of your computers in the Router and save the changes.

THIS IS IMPORTANT!! After cloning the MAC address and saving the changes, unplug the power to the Router. Next, you MUST restart the Cable Modem when you change the MAC address of the first device connected to it. The Modem will remember the MAC address of what was connected to it until it is powered off, this will prevent it from accepting a new MAC address. To do this you need to unplug the power cord from the Cable Modem AND remove the backup battery from the Modem as well if it has one. Pause for a moment and reconnect the power to the Cable Modem ONLY. Give it a about one minute to boot, then reconnect the power cord to the Router. You should now have a new IP address.
