Nov 24, 2009 · I'm trying to write a script to get the IP and MAC addresses from a remote subnet and then look up each MAC in a text file to determine what kind of device it is. I can pull the address from computers using WMI or nbtstat but what I'm most interested in is oddball objects like Zebra printers which don't seem to return anything. Any network packet that needs to travel from a certain ip address to another needs to know the destination ip's mac address. On windows there is a iphlpapi.dll file which has a function called SendARP which can be used to get the mac address of a given ip address. The first is to connect to the router via SNMP and read the atTable (1.3.6.1.2.1.3.1). This will give you a list of IP addresses matched to MAC addresses. You can use the SNMP functionality in Synapse to read the table. To connect to a router that's running SNMPv1 or SNMPv2c you will need the correct read community string. "I also really like the devices page, which lists all the devices connected to the router with a wireless or wired connection, and it even allows you to edit the name, and appears to store the information by MAC address, so that even if the device reconnects and is assigned a different IP, the router will remember the device name. Easy way is to find out using the ipconfig command in WIndows' Command Prompt, or System Preferences on OS X. What you are looking for in WIndows is the Default Gateway value. In OS X, you will see either Gateway or Router, with an IP Address listed. That IP should be your router. If you have access to the core router on your network you can track MAC to IP addresses by looking at the ARP table. In a Cisco router the query: Show arp | include "insert the MAC here" will display the corresponding IP address. This works while the device is connected to the network and until the arp cache times out after it has disconnected.
