Execute arp -a to print a list of IP and MAC addresses.Execute ping command ping 192.168.0.2 (NOTE: the instrument does not respond to ping).But I need to know the IP address before opening a socket (WinSock on Windows, sys/socket on OS X and Linux).Ĭurrently I use a very dirty way as shown below. I would like to write a C/C++ application which talks with the instrument using a socket connection. I know the MAC address of the instrument, but please assume that its IP address is unknown. The PC and the instrument are directly connected over a UDP socket with a CAT5 cable. In my case, there are only two devices: a very normal PC (192.168.0.1) and a scientific instrument which has an arbitrary IP address (192.168.0.xxx) hard coded in its ROM. Based on the MAC addresses, it was also able to accurately identify the right manufacturer for each device.I am looking for an easy way to convert a MAC address to the corresponding IP address in a local network. In my tests, Find MAC Address did a stellar job and was able to find the correct MAC address for every device connected to my network: a wireless router, multiple PCs, a Macbook, a home server, and even a Xoom Android tablet.

There’s an easy way to do it : Get LizardSystems‘s Find MAC Address ($30 for business use, 30-day free trial free for non-commercial use).įind MAC Address makes it exceptionally easy to find the MAC address of all devices on your network, and lets you set network IP ranges to scan.Simply tell the program the range of IP addresses on your network, click a button, and it looks at every address, ferreting out the MAC address for any device using that IP address. And even then, it may not work, because people may have connected tablets or smartphones to the network, and you may not know every person who has done that.

Having to manually go to every computer on the network, and taking the time to run tools to find out every device’s MAC address is extremely time-consuming. Every network adapter has what is called a Media Access Control address that uniquely identifies it.
