IP from MAC Address of a computer not in my network(remote)

Question

I do not know if this is even a valid question but I am trying to get the IP address of a computer that I try to remotely connect to via TightVNC.

I have checked some answers on the SO, but they were mostly about the ARP-table for finding the ip-mac on the current network, not on a remote computer.

Unfortunately I only took note of local IP and MAC address of the remote computer when leaving it, but right after going to holidays, I realized I do not know the actual global IP. Now I am wondering whether there is a way to know the IP via a running PC with a specific IP.

Maybe related to this question, I was wondering if there is anyway that I can check the recent IP's with my current Windows computer which it has used, so I would know the IP range of the network that I used in the previous days and use that to find my remote PC.

Answer 1

You should use a DDNS server, like http://www.noip.com/ where you install a software in your remote PC, and will update the IP in the no-ip server, now you will be able to connect to that remote PC, using a name like remote_pc_from_A.Yazdiha.no-ip.org in your ThigthVNC client.

This Batch Code will fetch the below Details,

1. PC Name
2. IP Address
3. MAC Address
4. Computer Description(If Available)

Please save the below code in anyname.bat format and run it. It will output the results in a separate text file.
