Question : to get IP address from MAC address

Hi,

I have a modul. It has an IP address and a MAC address. I connected it to my PC with ethernet cable. While I was working with it, I changed it's IP address and it gave an error. Then I can't reach to the modul with IP address.
I know the MAC address..
I have a program IP scanner. I wanted to scan all the IPs on the LAN but it takes long time..
I wonder if I can get the IP address from MAC address?Or how can I solve this problem?
Thanks

Answer : to get IP address from MAC address

Discovering IP addresses and MAC addresses on your LAN

There are a few ways to do this; the first relies on ALL your network devices answering to a broadcast ping (i.e. ping 192.168.1.255) more often than not this doesn’t work.

The reason you want to do this is, once you have pinged an IP address it is listed in your arp table (you can view your arp table from command line with the arp –a command.

As you don't want to manually ping every address, there’s an easier way.

1. Download the freeware utility winping http://www.webattack.com/get/wping.shtml
2. Start winping click landiscovery
3. Put your network address in at the top and click start
4. When its done Click Start >run >cmd {enter}
5. At command line type arp-a>>c:\ip.txt

Look on the root of your C drive for the file called ip.txt and there you go :)
