192.168.100.1 is a private IP address that can be assigned to any device on a local network that's configured to use this address range. This means that it might be assigned to a laptop, smart TV, smartphone, desktop computer, tablet, or Chromecast. It may also be assigned as the default IP address for some router models, meaning that it's the built-in IP address that the device uses when it's shipped from the manufacturer.

192.168.100.1 and 192.168.1.100 are easily confused with each other. Home networks use 192.168.1.x addressing (like 192.168.1.1) much more often than 192.168.100.x.

How to Connect to a 192.168.100.1 Router

Administrators can 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 http://192.168.100.1, then 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 password and username.

Administrators can change the router IP address from another default or custom number to 192.168.100.1. 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 192.168.100.1 over any other IP address.

Most routers do not use 192.168.100.1 as the default IP address but instead employ 192.168.1.1, 192.168.0.1, 192.168.1.254, or 192.168.10.1.

Here's a list of default IP addresses for several routers and modems, along with the corresponding default passwords and default usernames:

192.168.100.1 as a Client IP Address

An administrator can choose to assign 192.168.100.1 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, the router must be configured to include 192.168.100.1 in the range (pool) of addresses that it allocates. If a router starts its DHCP range at 192.168.1.1, tens of thousands of addresses exist in the range with lower numbers, making it highly unlikely that 192.168.100.1 ever gets used. Administrators more commonly assign 192.168.100.1 to be the first address in the DHCP range so that not only will 192.168.100.1 be used but also 192.168.100.2, 192.168.100.3, and so on.

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

More Information on 192.168.100.1

192.168.100.1 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 (LAN).

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 192.168.100.1 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 192.168.100.1 to one device even though another is using it as a static address.
