Find the IP address of your home router

ios6.routeripcrop2

In an upcoming blog I expect to write about configuring a home router, which requires logging on to it. This, in turn, requires knowing the IP address of the router. Non-techies typically don't know anything about IP addresses, let alone the one assigned to their router. Since I expect the upcoming blog to be fairly long, I decided to start with this cheat sheet for learning the IP address of a router.

All routers have a web-based interface and, thus, are configured with a web browser. While some routers can be accessed by name (they typically intercept DNS queries), they all can be accessed by their IP address. 

Full access to the router requires a userid and password, but to even get prompted for this, you need to know the IP address. 

An IP address is written as four numbers separated by periods. Typical home networks use IP addresses that start with 192.168. Often the router will have an IP address such as 192.168.1.1 or 192.168.2.1. 

If your Internet Service Provider (ISP) installed your router, they know both its IP address and the userid/password for it. In my experience, the ISP never tells the customer any of this information up front. 

With a self-installed router, you can get the IP address (assuming it wasn't changed at installation) from the manufacturer's documentation. Sometimes it is on a label on the bottom of the router. 

Once a network has been set up, each computing device on the network knows the IP address of the router and will spill the beans if you know the secret handshake. Terminology can get in the way however.  

Apple devices refer to the router as "Router". Windows refers to it as the "Default Gateway", a term borrowed from TCP/IP. Chrome OS refers to the router as "Gateway". Android won't tell you the IP address of your router, forcing you to install an app. 

WINDOWS

Windows users can start a command prompt and type in "ipconfig" to see the Default Gateway. The output will look like this on Windows 7

Windows IP Configuration

Ethernet adapter Local Area Connection:

   Connection-specific DNS Suffix  . :

   IPv4 Address. . . . . . . . . . . : 192.168.5.29

   Subnet Mask . . . . . . . . . . . : 255.255.255.0

   Default Gateway . . . . . . . . : 192.168.5.1

The output of the command Windows XP is almost identical. On either system, if the computer is using Wi-Fi rather than Ethernet, look for "Wireless Network Connection" instead of "Local Area Connection".

The same ipconfig command works on the desktop side of Windows 8, which also identifies the router as "Default Gateway". A wireless connection on Windows 8 is called "Wireless LAN adapter Wi-Fi", while a wired connection is identified as "Ethernet adapter Ethernet".

iOS

On both iOS 9 (tested with 9.2) and iOS 8 (tested with 8.1.2 and 8.4.1), go to settings, then Wi-Fi, then click/press on the name of the wireless network you are connected to. The IP address of the router is identified as "Router" in the DHCP section. .

On iOS 7 (tested with 7.1.1), go to settings, then Wi-Fi, then click on the name of the wireless network you are connected to. As with iOS 8, the routers IP address is identified as "Router" in the DHCP section.  

On iOS 6, go to settings, then Wi-Fi, then click on the arrow to the right of the network you are connected to. The interface is similar to that shown above, the router IP address is identified as "Router". 

The instructions for iOS version 5 are identical to those for version 6. 

All the instructions above assume that the iOS device was assigned its IP address using DHCP. In the rare case where it has a static IP address, click on the Static tab (shown above) and, again, look for "Router".   

OS X

In Snow Leopard, go to Network preferences, click on the Advanced button, then on the TCP/IP tab. As with iOS, the router is identified as "Router". 

In Yosemite you can get the IP address of the router a few ways. 

One approach is a terminal command. Run terminal with Go -> Utilities -> Terminal, then enter: 

  netstat -nr | grep default

The output looks something like 

  Default 192.168.3.1   UGSc   317    2    en0

In this example, the routers IP address is 192.168.3.1. 

Another terminal command you can try is 

  route -n get default

Look for "gateway" on a line by itself. To the right of it is the IP address of the router. 

If using Wi-Fi on Yosemite, Option clicking on the Wi-Fi indicator causes the system to display more data than a normal click. Included in this additional data is the IP address of the router, identified as "Router". Option clicking did not display the router IP address in Lion, I'm not sure which release of OS X introduced it. 

A normal click on the Wi-Fi indicator also produces the router IP address if you look hard enough. Click on Open Network Preferences, then on the Wi-Fi network interface in left side column (should say "connected"), then click the Advanced... button, then the TCP/IP tab and look for "Router". Whew. 

If not using Wi-Fi, then: System Preferences -> Network -> click on the "connected" network interface in the column on the left -> Advanced... button -> TCP/IP tab and look for "Router". 

If that's not enough, the IP address is also available in the System Information utility (Go -> Utilities -> System Information). Click on Network in the left side column, then Wi-Fi in the top pane (not the left pane), and look for "Router" in the IPv4 section.

ANDROID

Both Android versions 5.1 and 6.0 do not report the router IP address as part of the Wi-Fi settings display.

WiFi network information in Android 5.1 and 6.0

This carries on a long tradition of keeping users in the dark. Android versions 4.4.4,  4.4.2 and 2.3 also failed to provide the router IP address. These older versions would at least report is the IP address of your device, but this has been replaced in version 5.1 with the radio frequency band used by the network you are connected to. 

As they say though, there's an app for that. 

My favorite app for network information is Fing, which I wrote about last year. Fing is designed to take an inventory of the computing devices on your network. Run Fing and click on the top line, the one with the network name. It refers to the router as "Gateway" and the IP address is below the Local Address and above DNS. It may well be the same as the DNS address, this is not at all unusual. 

Another great app that shows the IP address of the router as a side benefit is WiFi Analyzer by farproc. In WiFi Analyzer, go to the AP list screen and click on the top line, the one showing the name of the network you are connected to and your IP address. In the window that pops up, look for the "Gateway" IP address (it is above the Netmask). 

 

CHROME OS

On a Chromebook running Chrome OS version 50, there are three approaches. 

chromeos.routerip.settings

Chrome OS Wi-Fi settings

Go to the settings page, either by selecting "Settings" from the hamburger menu, or, by entering "chrome://settings" in the address bar. If using Wi-Fi, click on "Wi-Fi network" under Internet connection, then on the name/SSID of the network you are connected to. This opens a window with three tabs, Connection, Network and Proxy. Click on the Network tab as shown above. The router is identified as "Gateway".

Alternatively, you can enter "chrome://system" in the address bar and scroll down to the "routes" section shown above. The text to the right will say "default via" followed by the IP address of the router. Although cut off in the screen shot above, the next line ends with device's IP address, just after "src".

chromeos.routerip.wlan0

Chrome OS network settings  

Another section, network-status, also has the router IP address but its the least user-friendly option.

Click on the gray Expand button. If the Chromebook is connected via Ethernet, look for the clump of data identified as "eth0". If it is connected wirelessly, look in the "wlan0" section as shown above. The router is identified as "Gateway".

NOT AGAIN 

Finally, so as not to have go through this again, I suggest writing the IP address of the router, along with the userid/password, on a piece of paper taped to the router face-down. 

Updates
June 23, 2014: There are a couple additional ways to learn the IP address of a router. More and more router manufacturers are offering smartphone apps to manage their routers. Very likely these apps will report the IP address of the router. Another management option for some routers is the website of the router manufacturer.
