TheHalf Posted July 24, 2006 CID Share Posted July 24, 2006 I was looking for an old thread reguarding this matter and I believe a member was interested in changing their IP addy, I also remember a senior member posting info on changing the NIC addy to change ones' IP. Anyhoo I wanted to inform anyone that if you have more than one ethernet port this can be done with realitive ease, here's what I have been doing. 1. I have cable and use a MotoSB5120 2. I have 3 ethernet ports (1 dual port Netelligent 10/100TX and 1 integrated 10/100/1000) -1st. With my PC on all I did was run the command prompt: ipconfig /flushdns, then ipconfig /release power down the modem and then the PC. -2nd. Unplug the the ethernet connection at the PC end and replug into ethernet port 2 or 3 and power up the PC (not the modem). -3rd. After PC is powered up power up the modem and wala. Conclusion: I can have my IP changed every time I do this procedure. *Footnote* I even logged 9 speed results at DSLReports because I did this.

FallowEarth Posted July 24, 2006 CID Share Posted July 24, 2006 Your IP address will change just by connecting the modem to another device (ie. another NIC). This is because the DHCP server is forced to create a new IP lease, since the IP lease is bound to the MAC of the client device, usually for a 72-hour period. You will likely have to reset the modem in order to clear the ARP/bridging table so that the new NIC gets an IP at all, but the IP lease to the old NIC will still be alive. Your method is a very thorough means of forcing a new IP lease from the DHCP server. Unfortunately, most PCs don't come with multiple NICs, so many people will be unable to take your approach. A lot of people are under the false impression that since they subscribe to 1 IP from their ISP, that their IP can't be changed from their end. This is incorrect, but the modem is only able to forward 1 IP at a time (meaning you cannot connect multiple devices to it simultaneously, and get multiple unique IPs) unless you purchase additional IPs.

TheHalf Posted July 24, 2006 Author CID Share Posted July 24, 2006 Your right FE. I am also glad for the info (NIC 101) lol. Anyhoo any PC did not come with multiple ethernet ports and the one one I have is from an old Prosignia server which I intend to install on my PC of 2007. All in all this was a thread to be murphed with an old topic (I couldn't find) and inform the starter on possibilities. Thanks again FE TheHalf Quote Link to comment Share on other sites More sharing options...
