Purpose of and 192.168.1.x IP Addresses

Many home computer networks use these IP addresses

How Home Routers Use the 192.168.1.x IP Address Range

Home routers by default define a range of IP addresses to be assigned to client devices via DHCP. Routers that use as their network gateway address typically assign DHCP addresses starting with It means that will be the second such address in line to be assigned, the third, the fourth, and so on. While DHCP does not require addresses to be assigned in sequential order like this, it is the normal behavior.

Consider the following example for a Wi-Fi home network:

  • The home administrator uses a PC to initially set up the router and home network. The PC is assigned IP address by the router.
  • A second PC is added to the network. This PC receives
  • A game console then joins the network. It receives
  • A phone connects to the router via Wi-Fi, receiving

Assigned addresses can be swapped over time. In the above example, if both the game console and phone are disconnected from the network for an extended period, their addresses return to the DHCP pool and could be reassigned in the opposite order depending on which device reconnects first. is a private (also called "non-routable") IP address. It means computers on the internet or other remote networks cannot communicate with that address directly without the assistance of intermediate routers. Messages from a home network router pertaining to refer to one of the local computers and not an outside device.

Configuring the 192.168.1.x IP Address Range

Any home network or other private network can use this same 192.168.1.x IP address range even if the router uses different settings by default. To set up a router for this specific range:

  1. Locate to the router's IP and DHCP settings; the location varies depending on the type of router but is often on a Setup menu.

  2. Set the router's local IP address to be or other 192.168.1.x value; the number you use in place of x should be a sufficiently low number to allow address space for clients.

  3. Set the DHCP starting IP address to be 192.168.1.x+1 - for example, if the router's IP address is chosen to be, then the starting IP address for clients can be
