All this for the low low price of $195! Sorry, but I'm not installing any app on my pc that's more expensive than the operating system.

"Colasoft MAC Scanner will send out ARP (Address Resolution Protocol) queries to the specified subnet and listen to the responses from all the hosts in the subnet, then list the MAC addresses and IP address in pairs." This is a bit different than finding MAC/ip addresses by pinging. (It is possible for some devices to have ping response disabled - my router, for example, does not respond to external pings.)

Colasoft MAC Scanner has free (personal, no registration/key) and PRO (commercial) versions. They look identical, except the free version, on startup, has a pop-up mentioning Colasoft's other products. This pop-up is easily dismissed and is less intrusive than those of other free products. The PRO version has no pop-up, but requires registration and is tied to the computer on which it is installed. Both versions maintain an internal database; apparently one can compare a current scan with differences within their database.

i got this through give away of the day now and key number is demanded before i can use kindly help at this exigent ffiyinfoluwa@yahoo,com my email

Strange: the program showed IP x.x.x.255 and that one is not assigned to any device on the network, also not the router:

And the mac of 255 is the same as another IP and also the manufacturer is from another ip.
The results are different between .TXT and .CSCNTAB, different number of ip:

MAC = Media Access Control code

You ask $195 for this?

what makes your product better than:

https://nmap.org/ (NMap)

https://nmap.org/zenmap/ (ZenMap)

http://www.advanced-ip-scanner.com/

https://angryip.org/

of those I gravitate towards Angry IP Scanner:

"Angry IP scanner simply pings each IP address to check if it’s alive, then optionally it is resolving its hostname, determines the MAC address, scans ports, etc. The amount of gathered data about each host can be extended with plugins."

plugins are good not to mention the source code is "open"

Installation of this minor version upgrade of previous giveaway version 2.2 demands complete uninstalation of the previous version then restarting the setup.exe The program will need re-activation with the new license code included in the readme.txt and the provided setup.exe is unwrapped which will make things easier for some. The previous versions database of MACs found is LOST in the uninstallation of the previous version so if you want to keep it you may want to try exporting the database and then try importing it into the new installation afterwards... I did not know this so have lost the previous historical database of MAC's discovered over a few different LANs this machines been on.
no great loss as it seems more a curiosity than a serious tool. Only use I can see for this is spotting interlopers on a WiFi equipped LAN or LANs with many spare ethernet ports around a factory or warren of offices in a large structure.

From included release notes text file included with this installation:

Colasoft MAC Scanner 2.3 - 2016.05
---------------------------------------------------
Bug Fixed:
Host Name is added with letter D.
Host Name and Workgroup information are swapped.


and that's the listed changes between this and the previous 2.2 we had in earlier giveaway several years ago.

Installed and working on Win 10 (64) with no problems ... Program isn't really that much use, it basically shows IP & MAC addresses and lets you store the info as a .txt file and that's just about it. Handy if you need to quickly find a devices IP or MAC but for serious users it isn't much use.
