[QUOTE="baggss, post: 1285644, member: 6762"] Agreed. Go to any hotel that has wired and wireless and swap between the two, you'll see different IP ranges. For the OP: The wireless router is assigning a [i]PRIVATE[/i] address to your computer as it is supposed to do. Your router uses the actual [i]PUBLIC[/i] IP from your ISP and shares access among various devices you may allow on the network, hence the different IP adress. When you hook up to the modem directly your computer now uses the [i]PUBLIC[/i] IP provide by your ISP and no other devices can share the network, unless your ISP allows you to have multiple [i]PUBLIC[/i] IPs. You can have some sort of sharing enabled from the computer itself, in which case the computer will act as a router and assign [i]PRIVATE[/i] IPs to other devices. There are dedicated [i]PRIVATE[/i] Network IP ranges that are standard for all routers / private shared networks. They are: 10.0.0.0 – 10.255.255.255 172.16.0.0 – 172.31.255.255 192.168.0.0 – 192.168.255.255 [url]http://en.wikipedia.org/wiki/Private_network[/url] Your router should allow the option to choose between any of those 3 blocks and may allow you to dedicate specific IPs within those block to specific devices on your network. In my case, on my home network, I have chosen to use the 10.x block and have set my router to allocate IPs from 10.0.0.2 to 10.0.0.200 for all my devices that connect to my router (both wirelessly and wired) but my actual ISP allocated [i]PUBLIC[/i] IP is used by my router to access the internet. You can only choose between those 3 block of [i]PRIVATE[/i] IPs for devices that connect to your router, there are no further options. If you wish to change your [i]PUBLIC[/i] IP address you need to contact your ISP and see what they can do. [/QUOTE]
