How do I find used IP addresses on my network?
The following procedures may be used to determine IP addresses of networked devices that are connected to your LAN.
- If you have a web access to a managed switch or router on the network, this can be used to identify all connected devices. The switch/router displays Static and Dynamic client lists with hostname, IP address and MAC address of the connected devices.
- You may also try pinging your network from a computer connected to the network, and lookup an arp table. On your computer, click [Start] -> [Run...] and type "cmd" and [Enter]. Type "ipconfig" to find your network address. The network address is found by performing a logical AND operation on your IP address and the subnet mask. For example, if you IP is 192.168.1.101 and subnet mask is 255.255.255.0, then the network address is 192.168.1.0. Ping your network's broadcast address, i.e. "ping 192.168.1.255". After that, perform "arp -a" to determine all the computing devices connected to the network.
- You may also use "netstat -r" command to find an IP address of all network routes. However, if your printer has problem communicating with other network devices, you may not be able to find IP address of the printer using "netstat" command.
