What Is the IP Address? might be a default gateway address or local client IP address

The IP address is a private IP address that might be used on a client device or assigned to a piece of network hardware as its default IP address.

What Is is more commonly seen in business computer networks than in home networks where routers normally use addresses in the 192.168.x.x series instead, such as or However, at-home devices might still be assigned the IP address, and it works just like any other.

If a client device has an IP address in the 10.0.0.x range, for example,, the router is using a similar IP address, most likely Some Cisco brand routers and Infinity routers supplied by Comcast commonly have as the default IP address.

How to Connect to a Router

Accessing a router that uses is as easy as using its URL like you would when opening any web page:

Once that page is loaded in the web browser, the router admin console is requested and asks for the admin password and username. login page

Private IP addresses such as can only be accessed locally behind the router. This means you cannot connect to a directly from outside of the network, like on the internet.

The only exception to this rule is if the network is set up with a publicly accessible domain name or you know the network IP address. A dynamic DNS service is one way to access a network from the internet using a common name. Default Password and Username

When a router is shipped, it comes with a built-in password and username combination that is needed to access the software and make changes to the network settings.

Here are some examples of username and password combinations for network hardware that uses

  • admin/password
  • [none]/public
  • [none]/[none]
  • Cisco/Cisco
  • admin/admin
  • cusadmin/highspeed

If the default password doesn't work, reset the router back to factory defaults so that the default username and password are restored. Once they're usable again, you can log in to the router with the default information.

These credentials are well-known and are posted online and in manuals, so it's unsafe to keep the default credentials active. The default password for the router is only useful so that you can log in to change it.

Problems With the IP Address

Users and administrators can encounter several issues when working with

Can't Connect to

The most common problem with the IP address, as with any IP address, is not being able to connect to the router when using the URL. There could be a number of things that cause this but the most common is that there aren't any devices on the network that use that IP address.

Use the ping command in Windows to determine whether a device on the local network is actively using Open Command Prompt and type:


You can't connect to a device that exists outside of your network, meaning that you can't ping or log in to a device unless it resides inside the local network you're using to access it (with the exception of the DDNS). Is Unresponsive

The device correctly assigned to might suddenly stop working due to technical failures on the device or with the network.

Incorrect Client Address Assignment

If DHCP is set up on the network and the address is applied in that way, then it's important to make sure that there aren't any devices that use as a static IP address.

If two devices have the same IP address, an IP address conflict causes network-wide issues for those devices.

Incorrect Device Address Assignment

An administrator must set up a router with a static IP address so that clients can rely on the address not changing.

On routers, this address is entered in one of the admin console pages, while business routers might use configuration files and command line scripts.

Mistyping this address, or entering the address in the wrong place, results in the device not being available on
