How to convert a MAC address to the corresponding IP address?

Question

I am looking for an easy way to convert a MAC address to the corresponding IP address in a local network. In my case, there are only two devices: a very normal PC (192.168.0

Answer 1

few days ago I was also facing this issue but after many struggle I got its solution below How MAC to IP address converter tool works? This MAC address converter can convert MAC address to IPv4 IP Address and convert MAC address to IPv6 IP Address, these internet protocol Addresses are very common to use. It takes MAC Address as input string and generates a query against given MAC to IP address and MAC conversion option like to MAC to IPV6 or MAC to IPV4 or both for MAC address conversion together. After this MAC conversion you can also revert MAC to IP conversion changes by using IPv6 to IPv4. Query generates an output response according to selected options.If you insert any invalid input produces an invalid input message response

How about try the system command arp within c++

system("arp");

This gives you a IP-MAC translation table.

There's no good, generic solution for this as it is the reverse of intended behavior. Lower level protocols are not supposed to need to be aware of higher layer ones, so operations at the MAC layer don't have any good way of finding out about IP addresses. And then you get into the situation you're in now. So you can either employ a hack like the code you already have, or you can tackle this from a different direction. Is there any non-code way to determine the IP address of the device before hand? Such as setting it explicitly or putting it in a configuration file for your app. Alternatively, can you have the device send out spurious ARP requests? The PC should update its ARP cache based off of incoming requests as well as responses to requests it made.

We had to do this a while back, but I don't think we got it working properly.

I don't have the API calls off-hand, but they're easy to find in the Windows API. That's what we used, so our solution wouldn't be portable to non-Windows systems.

In our case, we ran into the same hurdle--no easy translation. What we ended up having to do was get a list of all the NICs available, and then loop through each one trying to match our given MAC address against the MAC address obtained from the NIC structure.

Once we found a match, we looked up the IP address given to the NIC structure.

We kept on going to see if we found any other matches in order to log an error. It's a good thing we did, because I believe we did find it multiple times, and it wasn't due to a MAC address being cloned.

That's when we learned that this would be an even harder problem, and we decided to abandon the whole thing and stick to just IP addresses.
