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
-> Discover the SMB domain if any configured
-> Hostname resolution: DNS, mDNS (Apple devices) and SMB (Windows devices)
-> Custom hostname edition
-> Custom comment for each device
-> Export results in CSV files
-> Hide/show each column
-> Align each column as you want
-> No limitation on the number of devices found !

Comparison with the LanScan Pro edition:
-> Only 4 hostnames are fully displayed - You'll see the first 3 chars of the others

Since v4, it's preferred to buy the In-App purchase in LanScan Free edition than buying the LanScan Pro application.

Does the job

This seems to do the job (for IP-4 anyway). Some recent reviews have complained that devices as only listed as Apple with no hostname. As I understand it this is not a limitiation of the scanner, rather a reflection of the fact that Apple devices don’t broadcast their node name by default. It’s a pain to have to check them out one-by-one, but at least you can change the names in the scanner/add comments to identify the devices thereon in.

I don’t see IP-6 support, which is a pity. Add IP-6 for 5 stars.

Does what it says on the tin.

Had Lanscan Pro before this, have just switched to this version, basically the same, works reliably as usual, though sometimes multiple scans are required to pick up all devices, not a big deal though. Would recommend.

Lovely little app

Big love for LanScan. It’s ideal for picking up whats on a network and tracking down those pesky things that people have plugged in and think they’re getting away with it!
