What is a commercial address?

I have 2 PCs, and when I visit "what is my IP address?", I get the same exact IP address?

  • One PC is Ubuntu/Linux, the other is Windows 7. I get the same exact IP address when I visit "what is my IP address?" from both computers. They are connected to the Internet through a router and DSL modem. Is the IP address I keep getting the IP address for my router, or for my DSL modem? When I type "Ipconfig" at Windows command prompt, is the "subnet mask" the IP address for the PC I am using or for my router? I want to know the IP address for individual PCs. Thanks.

    Networks are designed that every device on a network must have a different IP address, else there could be some major communication problems. This is an issue when you have multiple computers sharing one internet connection. A modem is only capable of carrying one IP address to your house so it must be split using a router. A router uses a protocol called NAT - Network Address Translation. This masks your private network that is controlled by your router with one public IP address (the one in your modem). This prevents the confusion of an ISP talking with multiple computers. Once NAT occurs with outgoing traffic, all computers are talking to the internet using the same public IP address. So when you visit WhatIsMyIPAddress, it is revealing to you the public IP address of your modem, the one your ISP leased to you. When you try it on two different computers, both are talking over the same "line" and thus sharing the same public address. That's what NAT does. As for the subnet mask, that is also controlled by your router and dictates how many possible computers can have private IP addresses starting with 192.168.1.x. If the subnet mask is 255.255.255.0, then you can have 255 computers in the same "network". Subneting is very complex and cannot be explained easily. Simply put, the subnet mask is not an IP address. To reveal the private IP addresses on each computer, use the "ipconfig" command for windows. The "IP address" listed under the Ethernet Local Area Connection is that computers private IP address leased by your router. (In Ubuntu, I believe the command is "ifconfig" if "ipconfig" does not work.)

the IP address that you're getting is the router's/modem's ip address. since both computers are connected through the same router/modem, they get the same IP.

For windows PC you can get the IP address by using ipconfig command in command line but if u are not getting so then you can go graphically. For this just right click on the icon of your network connection.(Control Panel>Network connections>network options> right click on network name e.g. 'Local area connection' > select IP version through which u have connection > go through properties. And u can use ifconfig command for linux PC. The IP address of the interface is preceded by the term inetaddr, the broadcast address by Bcast, and the subnet mask by Mask.

when you go to tat site it is giving you the ISP IP address. not the machine IP. That is what the router does. it takes the ISP IP and makes it avalible for the other computers. to find the computer IP Click Start Run then type ipconfig /all

It's because they have the same IP address. I don't know the technical reasons for this other than they share the same connection to the Internet.

The IP address the site you visited sees (and tells you what it is) is only the router. The router assigns the IP addresses to each of your PC's and looks like this: 192.168.1.1 using IPconfig shows the IP address for that computer only. START - run then type ping 192.168.1.1 or what each of your PC's IP is and it'll return a response time if the computer is on and the firewall is not making it look invisible.

"what is my IP address" gives you the address of your MODEM. This is assigned by your DSL company. Both computers are attached to a router whitch shares the Single IP address you have assigned by your DSL provider.When you type ipconfig, you get the info for your PC attached to the router only. Subnet Mask Address only tells you if you are on the same subnet. The default gateway is the router's address. You'll find that both PC's have the same subnet and gateway. Gateway is the technical term for a router and other similar devices. A router Doesn't send you to the internet. It only shares the IP assigned by your internet provider(DSL in this case). When you tell the computer to go to google.com the router gives your computer a hall pass to use the internet. When the other computer wants to go to google.com it tells the router and the same thing happens. This is all happens in nonoseconds so you don't even realize whats going on.

This is the Internet (WAN) IP address of your router, not your pcs. In Windows, go to Run> cmd> ipconfig, this shows local (LAN) IP. the only problem with this is that ordinarily the ip addresses of each computer change every time you log them on

If you are looking for internal IP address (router IP) then go here: http://www.ipaddresslocation.org/router-ip-address.php http://www.find-ip-address.org/router-ip-address.php It will show you unique IP address from both of your PC (which is different). Your public IP address will be same on both PC and that;s what see the rest of the world: http://www.find-ip-address.org/ip-address-locator.php http://www.ipaddresslocation.org/ip-address-locator.php Good luck!
