I'm connected to a switch like my others business' computers. How can I get these IP addresses?

Of course, the switch is connected to a router and this to a modem...

arp -a

Given an IP address, you should be able to find the MAC address of the corresponding host.

(Note that this will need to be run on a machine that is on the same IP subnet as the machine you are trying to find).

Network Tracking Database


NetDB tracks all MAC addresses on your switches and ARP entries on your network over time. It supports extensive switch, VLAN and vendor code reports from a CLI or Web App. Can generate CSV reports, track the usage of static addresses and much more.
