It'll be interesting to see if you get any hits on that one, but I've never heard of one - at least not something generally available. That's because there's no lookup service for MACs as there is for IP addresses and hostnames (DNS), and IP addresses to MACs (ARP). There are a few tried and true techniques that may or may not suit you:
1. If you have an idea what subnet the box resides on and have access to the router that serves the subnet, you can look at the router's arp table for an entry. 2. If your own workstation is on that subnet, you can also check your own box's arp table. 3. You can also run a sniffer on your box to see if the MAC shows up in any packets. This would probably work even if you're on a switch network and can't span ports due to broadcast traffic. The only tool I've ever seen for this is CiscoWorks 2000 - which we use to query our routers' arp tables, and our switches' cam tables, and our DNS servers, and builds a master list of every MAC and IP address and hostname of every box plugged into every switch port on the network. ----- Original Message ----- From: <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Tuesday, July 01, 2003 1:54 AM Subject: Getting an IP address from a MAC address > Hi all, > > I was wondering if anyone knows of a tool which can determine an IP address > from a MAC address??? > I have found plenty of tools which will work the other way, but nothing for > what I am after. > > Thanks in advance > Steven P > > > -------------------------------------------------------------------------- - > Evaluating SSL VPNs' Consider NEOTERIS, chosen as leader by top analysts! > The Gartner Group just put Neoteris in the top of its Magic Quadrant, > while InStat has confirmed Neoteris as the leader in marketshare. > > Find out why, and see how you can get plug-n-play secure remote access in > about an hour, with no client, server changes, or ongoing maintenance. > > Visit us at: http://www.neoteris.com/promos/sf-6-9.htm > -------------------------------------------------------------------------- -- > > --------------------------------------------------------------------------- Evaluating SSL VPNs' Consider NEOTERIS, chosen as leader by top analysts!
