The most important aspect of your router — except for the connection that supplies power to the device — is its Web configuration screen. This is the heart, brain, and soul of your router. It’s the place where you go to set up all sorts of important options, including your router’s wireless networking and security settings, port forwarding for your software apps that need special access to the Internet, and all the special control options that allow you to dictate who/what accesses your network and when.
To access your router’s configuration screen, you need to type your device’s IP address — for D-Link routers, this is most often found within your device’s manual or printed on the underside of the router — into your Web browser’s address bar. That’s it. Easy-peasy.
Depending on the router model, you might also be able to use the device’s NetBIOS name instead of an IP address. In this case, just typing a URL like http://dlinkrouter into your browser’s address bar is all you need to connect up to the Web configuration password prompt. Again, you can find this name printed in your router’s manual or on its underside if your device supports such a feature.
But suppose your router is tough to get to and the last time you saw the manual was when you were throwing it in the recycling bin? Or perhaps you’ve already tried typing the IP address into your browser’s address bar and nothing happened. Never fear, I’ve got a solution.
In this case, access your Windows Command Prompt. In the Start menu, click on Accessories and then on Command Prompt and then type ipconfig into the black window that opens up. The black window will then be populated with information similar to the picture below:
Scroll up to the top of the screen and start looking for the first adapter that’s populated with three fields: An IP address, a subnet mask, and a default gateway. The gateway is the device that connects your system to the Internet — your router — and the IP address you’re looking at is your router’s identifier. You can now type this number into your browser’s address bar to access the device’s Web configuration screen. And from there, you have access to the entire vault: Every possible configuration option that allows you to tweak your security, connectivity, and all sorts of other important options for maintaining an awesome home network.
This story, 'Finding Your Router’s IP Address ' was originally published by BrandPost.
Ever had to figure out the IP address of your or someone else’s wireless network so that you could change its settings? Most people setup their wireless networks right out of the box without any configuration and therefore have no idea what the IP address is.
However, these days you need to login and at least setup a secure password for your WiFi network that is different than the one assigned by default. In addition, it’s a good idea to change the router password also, so that someone else connected to your network can’t log into your router and change settings.
If you’re already connected to the wireless network, then it’s really easy to figure out the IP address of the router. If you’re not connected to WiFi, you must have access to an Ethernet connection.
You can only determine the router IP address from a device that is connected over WiFi or from a device connected by cable (Ethernet). Connecting by cable doesn’t require a password, so it’s an easy way to bypass WiFi security if you can’t remember the WiFi password anymore.
Connected to Router
If you’re connected by wire or wirelessly, you can simply open the command prompt and run a simple command. Go to Start, Run, and type in CMD. At the command prompt, type in ipconfig and press Enter.
Scroll down till you get to the heading that has Ethernet adapter Ethernet or Wireless LAN adapter Wi-Fi in the name. Usually, you’ll only see one, but computers with WiFi cards and Ethernet cards will see two listings. The IP address of the wireless access point is the IP address that is listed for Default Gateway.
It’s worth noting that the default gateway is actually just the IP address for the router that connects to the Internet. In certain networks with more than one router, this might be the IP address of your ISP router, but not necessarily your wireless router. To detect more than one router, check out the link in the paragraph below on scanning your network for devices.
Now you can go ahead and type that address into your browser and you should be see the login page for your router.
In my case, my default gateway is my Verizon Actiontec router that also acts as my wireless router. That’s about it! It’s pretty easy to get the IP address for the access point this way.
However, if you cannot run the command prompt for some reason or you need to find more than one router on the network, then you need a network scanning tool. Make sure to check out my previous post on how to scan your network for devices, which will show you not only how to get the IP address for all routers, but also for any other device connected to the network.
Not Connected to Router
If you’re not connected to the router via WiFi or via Ethernet, you won’t be able to figure out the router IP address unless the network doesn’t use encryption. If there is a password set on the WiFi network, you’re out of luck.
However, you can still get some information about wireless networks you’re not connected to by using some third-party tools. They won’t be able to give you a lot of information, but it could help you find a hidden wireless network.
Find Ip Addresses On Router Password
For example, let’s say you go to your school library and you know there is a wireless network there, but SSID broadcast is turned off for security reasons. Even though it’s not secure at all, people use it to try and prevent others from connecting to their wireless network.
In this type of case, you need a WiFi network detection tool. You can use a tool like Xirrus WiFi Inspector to make sure the wireless network actually exists. WiFi Inspector is a program that can detect wireless networks even if SSID broadcast is turned off.
In order to download it, you have to fill out a bunch of info, but thankfully you can just make up everything and it’ll let you download it. When you run it, it’ll give you a list of all the networks in your vicinity. Note that Windows cannot detect networks that have SSID turned off.
If you are connected to the network, it will be able to display the Gateway, DNS server, MAC address, etc. If not, you’ll only see the info in the middle section that shows you the SSID, signal strength, network mode (a/b/g/n/ac), encryption (WPA, WPA2, etc.), channel and frequency.
So to recap, you need to be connected via WiFi or Ethernet in order to figure out the IP address for the default gateway using the command prompt. If there is more than one router on your network, you’ll need to scan your network using the tools I mentioned in my previous post.
Lastly, if you have no connection to the network, you can still get basic information about wireless networks using a WiFi detection tool. If you have any questions, feel free to comment. Enjoy!
Is there a way to get a list of all valid IP addresses in a local network?
I mean all IP addresses that each user is using in the network.

Install nmap,
then
or more comonly
will scan the entire .1 to .254 range
This does a simple ping scan in the entire subnet to see which all host's are online.

Try following steps:
- Type
ipconfig
(orifconfig
on Linux) at command prompt. This will give you the IP address of your own machine. For example, your machine's IP address is 192.168.1.6. So your broadcast IP address is 192.168.1.255. - Ping your broadcast IP address
ping 192.168.1.255
(may require-b
on Linux) - Now type
arp -a
. You will get the list of all IP addresses on your segment.

If you want to see which IP addresses are in use on a specific subnet then there are several different IP Address managers.
Try Angry IP Scanner or Solarwinds or Advanced IP Scanner

A home broadband router has two IP addresses—one is its own private address on the local network and the other is the external, public IP address that's used for communicating with outside networks on the internet.
How to Find the Router's External IP Address
The external facing address managed by a router is set when it connects to the internet service provider with a broadband modem. This address can be seen from web-based IP lookup services such as IP Chicken and also from within the router itself.
It's a similar process with other manufacturers, but on Linksys routers, you can see the public IP address on the Status page in the Internet section. NETGEAR routers might call this address the Internet Port IP Address and have it listed in the Maintenance > Router Status screen.
How to Find the Router's Local IP Address
Home routers have their local address set to a default, private IP address number. It's usually the same address for the other models from that manufacturer, and it can be seen in the manufacturer's documentation.
You can also check this IP address in the router's settings. For example, most Linksys routers list the private address, called the Local IP Address in the Setup > Basic Setup screen. A NETGEAR router might call it a Gateway IP Address on the Maintenance > Router Status page.
Here are the default local IP addresses for some of the most popular brands of routers:
- Linksys routers usually use 192.168.1.1 for their default internal address
- D-Link and NETGEAR routers are most commonly set to 192.168.0.1
- Cisco routers are often 192.168.10.2, 192.168.1.254, or 192.168.1.1
- Some Belkin and SMC routers use 192.168.2.1
- U.S. Robotics routers use 192.168.123.254
Administrators have the option to change this IP address during router setup or at any time later in the router's administrative console.
Unlike other IP addresses on home networks that usually change periodically, the router's private IP address remains static (fixed) unless someone manually changes it.
Tip: There are a number of ways to find the local IP address of the router in Windows, Mac, and Linux operating systems if you'd rather not look at the router itself. You can do that by finding the default gateway address.
More Information on IP Addresses
The public IP address of a home network will probably change periodically because the ISP assigns dynamic addresses to most customers. These change over time as they're reallocated from the company's address pool.
These numbers apply to the traditional IPv4 addressing most commonly used on networks. The new IPv6 uses a different numbering system for its IP addresses although similar concepts apply.
On corporate networks, network discovery services based on Simple Network Management Protocol (SNMP) can automatically determine the IP addresses of routers and many other network devices.
Before you can even begin to troubleshoot most network or internet connection issues, you'll need to know the IP addresses assigned to the various hardware devices in your network.
Instructions in this article apply to Windows 10, Windows 8, and Windows 7.
How to Find Fixed IP Address of Device on LAN
Most troubleshooting steps involve working with commands and other tools that require that you know your device's IP addresses. For example, you'll certainly need to know the private IP address for your router and, if you use them on your network, the IP addresses for your switches, access points, bridges, repeaters, and other network hardware.
Almost all network devices are preconfigured at the factory to operate on a default IP address and most people don't change that default IP address when they install the device.
Before you complete the following steps, first check for your device in our Linksys, NETGEAR, D-Link, and Cisco default password lists.
If you know the IP address has been changed or your device isn't listed, go ahead and follow the instructions below.
Determine the IP Addresses of the Network Hardware on Your Network
It only takes a few minutes to determine the IP addresses of the network hardware on your network.
- Find the default gateway IP address for your computer's network connection.In almost all situations, this will be the private IP address for your router, the most external point on your local network.Now that you know your router's IP address, you can use it in the following steps to determine the IP addresses of the devices that sit between the computer you're using and the router on your local network.Your router's IP address in this context, is its private, not public IP address. The public, or external IP address, is what's used to interface with networks outside of your own, and isn't applicable for what we're doing here.
- Open Command Prompt. In modern versions of Windows, the easiest way to do that is by searching for cmd from the Start screen or Start menu. Use the Run dialog box (WIN+R) in any version of Windows.The Command Prompt functions very similarly between Windows operating systems, so these instructions should apply equally to any version of Windows including Windows 10, Windows 8, and Windows 7.
- At the prompt, execute the tracert command as shown below, and then press Enter:Replace 192.168.1.1 with your router's IP address that you determined in Step 1, which may be the same as this example IP address or not.Using the tracert command this way will show you every hop along the way to your router. Each hop represents a network device between the computer on which you're running the tracert command, and your router.
- Immediately below the prompt you should see results begin to populate.When the command is complete and you're returned to a prompt, you should see a message similar to Tracing route to 192.168.1.1 over a maximum of 30 hops, and then a separate line for each piece of hardware sitting between your computer and the router.The second line could say:Any IP addresses you see before the router's IP is a piece of network hardware sitting between your computer and the router.If you see more than one IP address before the router's IP address, you must have more than one network device between your computer and the router.If you see only the router's IP address, then you don't have any managed network hardware between your computer and router, though you might have simple devices like hubs and unmanaged switches.
- Now you have to match the IP address(es) you found with the hardware in your network. This shouldn't be difficult as long as you're aware of the physical devices that are a part of your particular network, like switches, access points, etc.Goodsprings fallout new vegas. Devices that sit at the endpoint of the network, like other computers, wireless printers, wireless-enabled smartphones, etc., will not show up in tracert results because they don't sit between your computer and the destination — the router in our example.It might help to know that the tracert command returns hops in the order they are found. This means, using the example in Step 4, that the device with the IP address of 192.168.86.1 is physically sitting between the computer you are using and the next device, which we happen to know is the router.
- You should now know the IP addresses of your network hardware.
This is a very simple method to identify the IP addresses of the hardware in your local network and requires a basic knowledge of what kind of hardware you have installed. Because of that, it's likely to provide clear information about your IP addresses only on simple networks like the kind you'd find in a home or small business.
