Change of IP adress...
 |
Hello Everyone.
Thank you for letting me join. And i have one question. How do i change my IP adress ? I have cable internet, Comcast. I am supposed to have dynamic IP which is supposed to change time to time. I have already tried turning off the computer and modem for 3 hours and that did not work. If i go and change the modem, would this do it ????

Why do you want the IP to change? A static IP address is something that people pay for!
Seriously though, there's no realistic way of forcing the ISP to give you a different address.
You could try opening a command prompt and typing "ipconfig /renew" without the quotes but the server may simply issue the same address again.

What if i release the ipadress and not use the modem for few days and turn it back on, then maybe i will get another ip adress?? Maybe in that time someone else will pick up that adress and i will get a new one??
i have dynamic ips for my cable broadband and it ahsnt changed in 3 years
If i am helpful, please give me reputation points.

The ISP Typically has a DHCP Lease setup for your location, which reads your modems MAC Address. These are typically set to 7 days, or 24 hours (depends on the ISP). If you get a new modem, or you leave your exsisting modem off for the length of the DHCP lease, then you will get a new ip address.

In that case, the ISP usually assigns an IP address per MAC address as has already been said. A MAC address is a physical hardware address associated with a networked piece of hardware. Changing your modem, however does not always change the IP address. In my case, my modem doesn't have its own IP address. It simply allows the router or whatever is connected through its ethernet port to communicate with my ISP. So in that case, there's an easier way: changing the MAC address on your computer. There are guides on how to do this (this one is for Windows) although you can change the MAC address on just about any kind of computer: Macs, Linux boxes, PCs, even routers.

As you can see, it takes a bit of work, but at the end of this you should (hopefully) have a new IP address. Also, if you're paranoid about security and changing your IP address, consider proxies and network security software to protect your privacy, and yourself from the hackers.
Hope this helps

As has been said, many ISPs allow you to retain your IP address for years. Some allow you to change it by doing a DHCP renew, but often that won't be enough.
