LanScan is a free, simple and efficient IPv4 network scanner that discovers all active devices on any subnet: the local one, or any public subnet that you configure.
-> Auto-detection of configured interfaces: Airport, Ethernet, Virtual interfaces ...
-> Scan the IP range you like, from 1 IP to the whole IPv4 address space!
-> Scan your local network with ARP packets
-> Scan public IP network ranges with Ping / SMB / mDNS packets
-> Display the IP address, MAC address, hostname (4 max) and vendor associated
-> Hostname resolution: DNS, mDNS (Apple devices) and SMB (Windows devices)
-> Custom hostname edition
-> Export results in CSV files
-> No limitation on the number of devices found !
Comparison with the Pro LanScan edition:
-> Only 4 hostnames are fully displayed - You'll see the first 3 chars of the others
What's New in Version 3.1
+ Fixed a crash when two successive scans are quickly launched
+ Fixed a crash when filtering results and content was updated at the same time
+ Updated MAC addresses vendors (+531)
Does exactly what it says
Very, *very* useful if you’re trying to get MAC address so as to assign static IP leases, sure beats getting up and running to each and every room with a pencil and paper :)
