How to Find the Fixed IP Address of a Device on a LAN
Most troubleshooting steps involve working with commands and other tools that require you to know your device’s IP addresses. You need to find out the private IP address for your router and the IP addresses for any switches, access points, bridges, repeaters, and other hardware in the network. Before you complete the following steps, check for your device in our Linksys, NETGEAR, D-Link, and Cisco default password lists. If the IP address was changed or your device isn’t listed, follow the instructions below.
Determine the IP Addresses of the Network Hardware on Your Network
Before you begin, find the default gateway IP address for your computer’s network connection. In most situations, this is the private IP address for the router, the most external point on a local network. Next, use the router’s IP address in the following steps to determine the IP addresses of the devices that sit between the computer and the router on your local network. This simple method to identify the IP addresses of the hardware in your local network requires basic knowledge of the hardware you installed. Because of that, it’s likely to provide clear information about your IP addresses only on simple networks like the kind found in a home or small business. For example, the first line might read: The second line could say: IP addresses that appear before the router’s IP is a piece of network hardware sitting between your computer and the router. If you see more than one IP address before the router’s IP address, there’s more than one network device between your computer and the router. If you see only the router’s IP address, you don’t have any managed network hardware between your computer and the router, though you might have simple devices like hubs and unmanaged switches.
