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
-> Open custom URL in browser
-> 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.

works great, fast and reliable

After suffering through the greedy "IP scan basic/home/pro" bait and switch of a competitor, I am pleased to say that LanScan is a fine reliable product. It's naming "discovery" is not as good as others (you end up having to add nearly every Hostname manually) but once that is done, it's fast and reliable.
(What gives me pause: the "pro" version has been discontinued and now they proudly proclaim that future updates will follow the in-app-purchase model. It appears Debookee-team has gone to the dark-side? Sadly. TIme will tell)

Developer Response ,

Hey xTexLutz ! Thanks for your kind words. Not sure what you mean by dark side of the in-app purchase, both LanScan+In-App and LanScan Pro had the same features since we started to code both app when in-app didn't exist. Simply a better user experience for users ! More info here : (or google "How we migrated our LanScan Pro users to LanScan on App Store")

Great utility if you have more than a few machines or lans to support

I picked up a copy a few years ago and used LanScan in the "free" mode. It's been fantastic to take a quick inventory of the machines on my lans.

Eventually, I had a need for the additional information so I ponied up the six dollars for the pro version (buy in-app, not the separate version).

This has made it so simple to find IP addresses for devices I cannot quickly get to or which don't have a way to view it. The built-in port scan is just gravey. Definitely worth the money.

Recently, I upgraded to Catalina and tried to do a scan on a machine with multiple interfaces. Though I had a problem, so I emailed the developer (accessed through the app's Help menu). On a Sunday, I got a response in 6 minutes. I was amazed. OK, so I probably won't always get the level of support every time, but I was happy.

Turns out it was a cockpit error, but the email clearly addressed my problem and contained everything I needed to use LanScan correctly.

Seems to work OK for wired network

Seems to find everything on my wired network, but doesn't seem to pick up any devices on my wireless network (which my Mac is also connected to), which is why I bought it.

Update: fast developer response and they are correct about security features in wireless network preventing it from seeing devices (which is good to know).

Developer Response ,

In that case, it means that your wireless network has security features to restrict communication between devices or ARP Proxy feature. Can you ping other devices on the wireless network? Contact for more debug
