How to Find the IP Address Range of Your Local Network

13/2/2025

The IP address range of a local network consists of the IP addresses assigned to devices within the same Local Area Network (LAN). This range is determined by the router's settings and subnet mask.

For a subnet mask of 255.255.255.0, up to 253 unique IP addresses can be assigned. However, some addresses are reserved for specific purposes:

  • 192.168.0.0 — Network address (identifies the network itself).
  • 192.168.0.1 — Typically assigned to the router.
  • 192.168.0.255 — Broadcast address (used to send messages to all devices on the network).

This means that devices, including the router, can use IP addresses from 192.168.0.1 to 192.168.0.254.

How to Determine Your Local Network's IP Range

You can find your network's IP range using one of these two methods

Method 1: Check Your Router's Settings

  1. Open a web browser and enter the router's IP address (e.g., 192.168.0.1 or 192.168.1.1).

  2. Log in using your credentials (default login: admin, password: admin, unless changed).

  3. Navigate to the LAN settings section. Look for the IP address range or DHCP settings, where the starting and sometimes ending addresses are listed. For example, if the router's IP is 192.168.0.1 and the subnet mask is 255.255.255.0, the available range will be 192.168.0.1 to 192.168.0.254.

Method 2: Use a Command on Your Computer

  1. Open Command Prompt (Win + R, type cmd, and press Enter).

  2. Type the command ipconfig and press Enter:

  3. Look for the IPv4 Address and Subnet Mask fields. Based on your IP address and subnet mask, determine the range. Example: If your IP is 192.168.0.68 and the subnet mask is 255.255.255.0, the range will be 192.168.0.1 to 192.168.0.254.
