Several different WAN router Ips? [belkin router] [ip changes]
Q: Ive been playing around with a Linksys router and Belkin. If I ever change the router, the external dynamic WAN IP is also changing. Why does this happen?
Best Answer: Use always trustful site for tracking your IP address.
As first your computer have 2 different IP addresses. One is router IP address and you can check it:
http://www.ipaddresslocation.org/router-…
http://www.find-ip-address.org/router-ip…
Another one is your external or WAN IP address::
http://www.ipaddresslocation.org/ip-addr…
http://www.find-ip-address.org/ip-addres…
See what they site above show you and you will know of the site that you have used for testing told you right.
Good luck!

Well… that depends. For Comcast in my area, the DHCP lease is tied to the MAC address of my DOCSIS modem, and I can change routers or plug in directly, and when I renew, I still have the same IP address. Every couple of months, I'll notice for some reason the IP address has changed, but it has nothing to do with the MAC address of my connected equipment.
Ditto with OOL. changing routers, NIc's etc has absolutely ZERO effect on my WAN IP addy. They sell it as a dynamic IP, but in reality I have only had it change 2 or 3xs over the past 3 years.

Re:it is tied to the MAC address of the hardware. get the MAC address of the one you have had, and find the place in the router configuration on the other one that is called "MAC Cloning" or spoofing. Enter the MAC address of your old router in there, and you should get the same IP as the old router.
Re:both routers seems to have its own IP that it likes, when i change to the linksys, its always the same, when i switch to teh belkin its always the same on respectively. I've been switching them out, and resetting my modem many times in the past two days, but they always seem to want to keep thier own WAN IPs for some strange reason. I don't even have to reset my cable modem, it just switches to its respective IP when i switch them in and out. I've had my Linksys IP for like 3 years, and would like to keep it.
Re:Exactly as Scott said. I drag the NIC in my router box into any new router box I am testing, so I can keep my IP without doing spoofing in freeBSD.

Re:Because you're making a new connection, and they obviously always reset the DHCP lease when you disconnect.
