How to Work With IP Address 192.168.100.1

This article explains how to work with the private IP address 192.168.100.1, 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 192.168.100.1 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 http://192.168.100.1, and press Enter.

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 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.

We gathered the default IP addresses, along with the corresponding default passwords and default usernames for routers and modems manufactured by Cisco, Linksys, NETGEAR, and D-Link.

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, you must configure the router 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 192.168.100.1 will be used and also 192.168.100.2, 192.168.100.3, 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 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.

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.
