Wireless Netowork and IP Address


OSNN Newbie
I don't know much about computers and 2 years ago when I set up my wirless network, I needed someone to help me as I couldn't get it operational.

I have a linksys wireless router and Comcast provides me with a cable internet connection. I am using WEP and I don't broadcast my IP and I asked to have my router configured to only give out 2 IP addresses. I'm operating in Windows XP home (SP2).

My question is about IP addresses. When I go on-line to sites that tell me what my IP address is. I always get the same IP address (24.125.xxx.yyy). Shouldn't these sites tell me that my IP is 192.168.x.xxx?

Also, with a dynamic IP, why do the sites always tell me the same IP? Shouldn't my IP change weekly?

Any input you might have would be appreciated.

It all depends. The 192.168.x.xx IP is the LAN IP address (local address) when you access the internet you have a WAN (public address) which is the 24.125.xxx.xxx address.

You stated that it doesn't change, this could be since the router is always online the IP lease time just keeps getting renewed so you don't get a new IP.
When you log into your router, look on your status page, under WAN IP you will see that 24.125-. Your router takes this number and converts it (NAT = network address translation) to a 192.168.x.x. So when you go to www.whatismyip.com it will show you what the routers public (or WAN) IP is. Your WAN IP will rotate every so often when your ISP changes it, but if you have a router on all the time it may not.

Hope this helps.

Not sure how that is on topic or helpful?

Ok so on topic no your ip will not change it is cable so chances are you will hold the same ip for a long time, if you were to unplug your cable modem from the network and wait 3 , 4 or 5 days maybe longer there is a chance someone will pick up your ip and when you go back you will end up with the next available ip in your area, some cable companies might change ip's after a certain time, and some might do it if your ip is under attack by someone.
