Public IP Address vs. Private IP Address. A router will connect to the gateway with an IP address in the range of 192.168.0.1 or 192.168.1.1. A command via the computer will allow you to determine the private IP address that has been assigned to your router. You can also simply log onto specialized sites to access this information. An IP address (or Internet Protocol address) identifies each networked computer and device on a network. When you sign up with Internet service and connect your modem, your ISP assigns you a public IP address. This address is how you communicate with all the other devices out there on the public Internet. Find your IP address for Windows XP and Vista by clicking the Start button. Step 3: Click Control Panel Click Control Panel, clicking Network and Internet, and then clicking Network and Sharing.
.Detect Your IP Address with Command PromptYour IP address (or Internet Protocol address) is a numeric identification number that detects your computer in a given network. It is used to communicate between nodes in a system network.Public IP Address vs. Private IP AddressWhen you connect to the internet through an ADSL modem, your computer has two network interfaces.A private interface is used to network computers connected to a router. Computers in this network typically have an IP address in the range of 192.168.0. or 192.168.1. A router will connect to the gateway with an IP address in the range of 192.168.0.1 or 192.168.1.1.
A command via the computer will allow you to determine the private IP address that has been assigned to your router.You can also simply log onto specialized sites to access this information.Find Your Private IP Address Command Prompt for Windows 2000/XP/VistaGo to Start Menu and select Run. Then, type cmd /k ipconfig /all.Your IP address will appear in an open window after a few seconds.Command Prompt for Windows 95/98If you are a Windows 95 or Windows 98 user, head to your Start Menu and select Run.
Then type winipcfg.Command for LinuxLinux users can find their IP address by typing in ifconfig as a root. Alternatively, you may also type in /sbin/ifconfig in a console as a user.Find Your Public IP AddressThe easiest way to find your public IP address is to head to. Simply click on the link to view the address.Some Sites Show Different IP AddressesYour ipconfig may often show a different IP address than that seen on sites such as whatismyip. If this is the case for you, there are two possible explanations.The first explanation is that you did not initially check the right interface. You may have multiple IP addresses corresponding to multiple modems or WiFi connections. Use ipconfig /all to view all interfaces.The second explanation is that you are behind a router, gateway, or proxy.
A router will perform address translation between the internet and your LAN (NAT). If this is the case, please refer to our tips on and.Note that whatismyip sees only the internet address of your router, while ipconfig only sees the address of your computer.Photo: © Vector - Shutterstock.com.

Computers prefer numbers, and the numbers they use as identifiers are called IP addresses.The 'IP' stands for 'internet protocol,' which is part of Transmission Control Protocol/internet Protocol (TPC/IP).
It's all called IP for short, and TCP/IP is the language used for communication by most networks. When it comes to your computer(s), there are actually several IP addresses involved. One is how the computer talks to the internet at large, which is the IP address of your. That IP address is generally assigned to the router by your internet service provider (ISP); the router, in turn, handles all the traffic from your computer out to the internet.
So even though a website only sees a request come in from the IP address on the router, the router knows how to route the information to/from the computer. (That's why it's called a router.). Computers on the internal networks, be it Wi-Fi or Ethernet, at home or in the office, have their own IP addresses assigned to them (usually by the router). That way, all the nodes on the internal network can also communicate. The protocol used by the router to assign IP addresses is called Dynamic Host Control Protocol (DHCP).If you have an IP address assigned, it's typically considered a 'dynamic IP' because it could be temporary; the router might give the node in question a different IP address at a later time (same with the IP address your ISP gives your router). However, you can set up 'static IP addresses' on computers so they never change—this can be important for some kinds of network communications, especially if it's crucial to be able to find that same node over and over.
You could also get a static IP for your router—which is handy if you run a web server, for example, but expect your ISP to charge extra.IP addresses are typically in the same format as a 32-bit number, shown as four decimal numbers each with a range of 0 to 255, separated by dots—each set of three numbers is called an octet. This format is used by IP version 4 (or IPv4). With it, you could—in theory—have 0.0.0.0 to 255.255.255.255 out there. However, this limited the world to a possible 4+ billion IP addresses, which isn't enough. So now, there's IPv6, which is 128-bit, and went from four to 16 octets. That's a lot more than 4 billion—it's a 34 with 37 zeros after it (or 2 to the 128 th power).
Technically, 340,282,366,920,938,463,463,374,607,431,768,211,455. That's a lot of IP addresses.That's all good to know, but how do you find your IP address? Find Your Internet/Public IP AddressThere may come a time when you need to know the IP address of your router, as assigned by your ISP. This can be particularly handy for things like calls or remote control software.What you'll also find is that there's lots of information about you attached to that IP address, specifically your ISP's name and your general location (called a GeoIP). That's because ISPs dole out a range of IP addresses.
Figuring out your provider and general location based on IP address is as simple as consulting a public list.The simplest way to check your router's public IP address is to search 'what is my IP?' With Google, that's all you see. There are plenty of sites out there that will show you the exact same thing. They see it simply because by visiting the site, your router has made a request, and thus revealed the IP address. Sites like and all go farther, showing off the names of your ISP, your city, and even maps.The GeoIP info is far from foolproof. Generally, you're going to get an approximation of location—where the provider is, not the actual computer. In visiting those sites, I was told I was in Ithaca, New York.and Syracuse, New York.
The design team utilized a variety of interpolation techniques on multiple parts of an image, such as transparency and reflection. To familiarize himself with the process, Andreev observed various 120 Hz television sets that incorporated two frames in producing an intermediate image, resulting in a smoother and clearer picture. Special effects Dmitry Andreev devised a framing system that gave the illusion of operating at 60 (FPS), despite running at 30FPS. Force unleashed 2 cheats.
One gave a latitude/longitude that put me in North Carolina (which could be where my ISP has a data center, for all I know). Be sure to log out of your, too. Getting a real address for the public IP address usually requires a search warrant taken to the ISP. Find Your Internal IP AddressEvery device that connects to your internal network, be it at home or the office, has an IP address (your PC, your smartphone, your smart TV, your network printer, etc.) It doesn't matter if it's using Wi-Fi or Ethernet. They've all got an IP address if they're talking to the internet, or each other, through your router. This is pretty much the same on all internal networks, because they're hidden behind the router, which routes all that communication in and out to the proper places. If you have a big internal network, another number called a subnet will help divide your network into groups.
The subnet mask used by most home networks is 255.255.255.0.So how do you find it? In Windows it requires the command prompt. Search for ' cmd' (without the quotes) using Windows search. In the resulting pop-up box, type ' ipconfig' (no quote marks).What is revealed is more than just the IP address: you'll see the IPv4 Address, the subnet mask, plus the Default Gateway (that's your router). Look above that row of data in the middle, and it shows the type of connection: 'Ethernet adapter Ethernet.'
If I was using Wi-Fi, it would have information under 'Wireless LAN adapter Wi-Fi.' On the Mac, it's a little less esoteric.
Go to the System Preferences, select Network, and it should be right there. Click the connection type on the left to see the IPs for each type.
You may need to click the TCP/IP tab at the top. Or you can go full geek and open the Terminal and type ' ipconfig' just like on Windows. On an iPhone, go into Settings Wi-Fi, and click the ' i' in a circle ( ) next to the network you're on. The IP address, subnet, and router (gateway) will all be there under the DHCP tab.If you need the IP address of other devices on your network, go into the router.
How you access your router depends on the brand and the software it runs. In general, you should be able to type the router's gateway IP address into a web browser on the same network to access it. From there, you need to navigate to something like 'attached devices' (that's what I get on my, pictured below).

From there you get a full list of all the devices currently (or recently) attached to the network—and that list includes the IP address assigned to each device.If you're really lucky, you've got a modern router (or set of routers, like a ) that can be controlled entirely with mobile apps. The app may make it a lot easier to find the IP address(es) you want.
