A List of Common Default Router IP Addresses

Here's the scenario: you are trying to fix a relative's network issues and you need to access their router's browser interface. We've all been there, fruitlessly pecking in combinations of 192.168.x.x. Unless you have every default router address tattooed on your forearm, you'll eventually encounter one that stumps you. 

When that happens, you can typically find the information with a simple command on Windows. Open the command prompt (Start > Run/Search for cmd) and then enter ipconfig. The address you need should be next to Default Gateway under your Local Area Connection, and it will often begin with 192.168. 

If you're looking for an equally handy default username and password list, this PDF has tons of information for just about every router manufacturer out there. Common default usernames include variations of admin (Admin, administrator, etc.), and the password is often admin, password, or simply left blank -- needless to say, it's good practice to change these upon setup.
