Ever see an IP address to reverse? Like finding a home address using a phone number? If you are in IT, you can sometimes come in a situation where you have a MAC address, but it is necessary to find out what the IP address is.
Determine The IP Address From a MAC Address
There are some ways you can do this. First of all, it is important to understand that the MAC address cannot be known for any PC. It can also be a printer or a MAC address for any other type of device on the network.
If you suspect that the MAC address is a printer, then first you have to check this site mention below to see if it matches a major manufacturer:
You can also find out whether the MAC address is from switch or other networking devices from HP, CISCO, etc. If you are sure that the MAC address is a computer, then you have to try the methods below to determine the IP address.
Method 1 – DHCP Server
The easiest way to get an IP address from a MAC address is to check the DHCP server if possible. Whether you are in a corporate environment or you are at home, each and every computer is being assigned an IP address from a DHCP server (unless it is a stable network, which is rare).
You can either go to the DHCP console on the Windows Server 2003/2008 or you can log in to your wireless router at your home, if you are using it.
Just go to the Address Leases under the Scope and then you can see both the client IP address and the Unique ID, which is the MAC address.
If you have a wireless router at your home, then it will vary depending on the brand (Belkin, Netgear, LinkSys, etc.). But basically, there should be a section to see all the existing devices connected to the wireless network.
On my AT&T U-Verse box, it’s on the right side of the Home page and then you have to simply click on the Device Details to see the MAC address.
Method 2 – Ping Broadcast Address
Another way to do this is to use a useful command called ARP (Address Resolution Protocol) in Windows if you cannot access your DHCP server.
Basically, you have to ping the broadcast address on your network from any Windows machine and then you have to check out the ARP table later.
If you do 192.168.1.X subnet with a mask of 255.255.255.0, you will ping 192.168.1.255. When you do ping, you will get the Request Timed Out all four times, but do not worry.
Next, you have to type in the following command
Now you will get a list of all connected devices on your network with your physical addresses!
Method 3 – Free Equipment
Finally, you can use a free program to get an IP address from a MAC address. This is called CC Get MAC Address and it can be downloaded here:
Before you can use it, however, you need to scan all the IP addresses in your subnet to make it work. The program itself has an auto-scan facility which is in an IP range.
You can use a free program, called an Advanced IP Scanner, which will do the same thing and is a program that is fully dedicated to scanning the IP address:
You can also use the IP Scanner and then you can run arp -a command only to get the list of IP/MAC Addresses.
