I just wonder if someone can tell me if there is an existing shareware that can resolve IP addresses by giving the Mac Address as reference?

This is called RARP, or Reverse Address Resolution Protocol. It comes with all network operating systems, including Windows.

Note, however, that RARP (and ARP) can only resolve local addresses, as in ones on your local subnetwork.

For your local net, if you are using DHCP, look in the dhcp manager it will give you the mac for all Ip address currently leased out.

Hi, if the machine you like to resolve is on the same subnet, you can do this in DOS command by ARP -a. This will show you all known IP addresses from your machine. If the machine you want to resolve is unknown, do a ping x.x.x.255 where x.x.x is your network address, and then arp -a will show you what you need. Hope this help.

www.ipswitch.com has a utility that will automatically ping every IP address on your network. Then ARP -a will let you look up the address. I sent them a product enhancement request a few months ago to do what you ask (ping by mac address or a rarp.EXE program so maybe they've written it by now.

huben, unfortunatly not all hosts reply to a broadcast ping, so your method might work or might not.
