On Friday we released NetScanTools Basic 2.1 - our first update to this software since January 2010. This is our freeware version of NetScanTools. It has just a few helpful tools that introduce people to the NetScanTools Product line.
Tools:
DNS Tools - simple query (ipv4 to hostname etc.), Who Am I (shows your IPv4 address, hostname and DNS servers), Test Default DNS (takes IP address or hostname and asks each default DNS server for translation).
Ping - uses standard ICMP ping to contact an IPv4 or hostname.
Graphical Ping - uses standard ICMP ping to contact an IPv4 or hostname and it graphs the response times over time.
Traceroute - uses ICMP packets to show the route between your computer and a target computer.
Ping Scanner - uses ICMP packets to ping every IPv4 address between a start and ending IPv4 address.
Whois - shows basic whois information for around 70 domain extensions and IPv4 addresses.
These tools are simplified in comparison to NetScanTools Pro which means you don't have all the options available and you only get one mode of operation - for example traceroute is ICMP only instead of ICMP, UDP, TCP etc.
Have a look and enjoy!

NetScanTools (tm) Basic Edition 2.0 Released Jan 14, 2010
This update to the Freeware Basic Edition changes the layout of the left control panel to make it less confusing. I also added the registered trademark notice for NetScanTools. The SQLite DLL to the latest version as was the whois database it works with. The biggest change was a switch to Inno Setup away from the old Wise installer. This reduced the size of the final installation .exe nearly 1 MB and it gives full compatibility with Windows 7. Speaking of Windows 7, NetScanTools Basic is fully Windows 7 compatible.

ARP Scan versus Ping Sweep
Today I had a user ask me what the difference was between ARP Scan and Ping Sweep (NetScanner) and why he gets different results when running them on his 192.168.0.x subnet.
Here was my answer:
There is a difference between ARP Scan and Ping Sweep. When you do an ARP Scan of a subnet, all devices that communicate with IPv4 on that subnet must respond to ARP packets. If they don't respond they cannot communicate with any other machine. This even applies to devices that are running firewalls and do not respond to ICMP echo request packets (ping packets).
When you use Ping Sweep on that same subnet, you are sending ICMP echo request packets to every device. If the device (computer) is running a third party 'personal' firewall or even something like the built-in Windows Firewall, it may not respond depending on the firewall settings. So you will see fewer devices respond with Ping Sweep than with ARP Scan.
They both have their uses because ARP Scan does not work once it crosses a router to another subnet or WAN. ICMP packets generated by Ping Sweep are routed unless deliberately blocked, even across the internet.

NetScanTools (tm) Basic Edition Released May 14, 2009
What? another NetScanTools?
Yes. When we stopped producing NetScanTools Standard 5.1 in August 2004, we left a whole lot of registered users without any alternative. Business users who wanted to move up opted for NetScanTools Pro, but many, many home and small business users could not justify or afford the upgrade, so they either kept using on NetScanTools Standard (yes, we still hear from people who have used it for years) or they found something else.
Two weeks ago we decided to make a new program using the latest Visual C++ 2008 compiler along with an updated interface -- that's right two (2) weeks ago. Now there is a new program created from almost scratch and it is completely finished! And it works fine on Windows 7, Vista 32/64, 2008, 2003, XP and even Windows 2000.
This new tool has simplified versions of six tools: Ping, Traceroute, Ping Scan, Graphical Ping, DNS Tools and Whois. They are very usable versions of more advanced tools found in NetScanTools Pro. There are embedded web pages comparing the NetScanTools Basic versions of the tools with the NetScanTools Pro versions. Plus we show you what other tools are available in NetScanTools Pro -- just in case you are interested.
It is now our entry level program.
And it's freeware. Try it. Enjoy it. And don't forget to give us feedback on the About NetScanTools Basic page.
