LanScan is a free Mac application that scans the network or a range of IP addresses. This utility gives you access to the hostname (if one is assigned for that PC/IP), its MAC physical addresses, and the vendor of that network adapter.
This program features an intuitive interface, provides you with accurate information, and uses minimum CPU resources while running on your computer. LanScan also offers you an option that comes in handy if you want to scan a LAN using the eth1 or the wireless interface.
Another important advantage is the fact that the application comes with an integrated search tool that helps you locate the information you need within moments.
In addition, you can edit hostnames, export the offered details to a TXT file, and empty the stored records if necessary.
In my testing, the program worked perfectly. It was very simple to handle this application even though I don't have much experience in dealing with network-related utilities.
All in all, LanScan might prove to be of good use to Mac users who wish to identify all active devices on any subnet.
