You’re working on a network and trying to find a device, but can’t remember the IP address and you don’t have NMAP handy…This is particularly significant when dealing with network printers, etc.
The two useful sequences are:
1. You may 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 your 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 using a broadcast address, i.e. “ping 192.168.1.255”. After that, perform “arp -a” to determine all the computing devices connected to the network. One of the IP found will be your missing device.
2. You may also use “netstat -r” command to find an IP address of all network routes. However, if your device has problem communicating with other network devices, you may not be able to find IP address of the printer using “netstat” command.
