How to Work With IP Address

Connect to a router at to make admin changes

What to Know

  • Connect to a router: In a web browser, go to the navigation bar, enter, and press Enter.
  • An admin can assign to any device on a local network dynamically through DHCP or manually to form a static IP address.
  • is a private IPv4 network address, so it's only relevant within a local area network (LAN).

This article explains how to work with the private IP address, which may be assigned to a device such as a laptop, smart TV, or computer. It may also be assigned as the default, built-in IP address for some router models.

How to Connect to a Router

Administrators log in to a router at this IP address by accessing it like any other URL. In a web browser, go to the navigation bar, enter, and press Enter.

Type the address exactly as shown. A mistake such as 192..168.100.1 will not open the router configuration page.

Opening the above address triggers the web browser to prompt for the router admin username and password.

Administrators can change the router IP address from another default or custom number to Some might choose to make this change so that it's easier to remember the address for logging in to the router, but there is no particular benefit to using over any other IP address.

Most routers do not use as the default IP address but instead employ,,, or

An administrator can choose to assign to any device on a local network, not only to the router. This can be done dynamically through DHCP or manually to form a static IP address.

To use DHCP, you must configure the router to include in the range (pool) of addresses that it allocates. If a router starts its DHCP range at, tens of thousands of addresses exist in the range with lower numbers, making it highly unlikely that ever gets used. Administrators more commonly assign to be the first address in the DHCP range so that will be used and also,, and so on.

With a manual, static IP address assignment, the administrator must set up the router's network mask to support the IP address. See our explanation of subnet masks for more information.

More Information on is a private IPv4 network address, meaning that you cannot connect to the client device or router from outside the home network like you can with a public IP address. Its use is only relevant within a local area network.

The exception to this rule is if the network uses a dynamic DNS service, which connects to the internal network using a publicly accessible hostname.

Neither routers nor clients experience any difference in network performance or security from having this address compared to any other private network address.

Only one device should be assigned the IP address. Administrators should avoid manually assigning this address when it belongs to a router's DHCP address range. Otherwise, IP address conflicts can result since the router can dynamically assign to one device even though another is using it as a static address. and are easily confused with each other. Home networks use 192.168.1.x addressing (like much more often than 192.168.100.x.
