This version has been superceded by Network Tools 2. This app was inspired by Ping Tool. It implements all user suggestions found on that thread. Shown: Trace Route (Advanced), Ping This is a relatively advanced network tool. Simply select which you want to perform, enter a domain name or IP address, how many packets/hops to perform, and click start. Once it has started, changing any of the above settings will stop it. In order to perform an infinite ping, enter -1 into Packets field. It will turn cyan to confirm an infinite run is selected. Fields that have an invalid value will turn pink. You can scan multiple port numbers by placing a comma between them. Requires .NET Framework 2.0 or newer. Usage: Action Input Description Example 1 Ping A domain name or IP address. example.com or 220.127.116.11 2 Trace Route A domain name or IP address. example.com or 18.104.22.168 3 Trace Route (Advanced) A domain name or IP address. example.com or 22.214.171.124 4 Port Scan Port numbers delimited by commas and ranges with a hypen. 80,90,800-810 5 Remote Port Scan IP or domain name followed by a colon, followed by the port numbers (same as Port Scan). Separate many domain/ip queries using a semicolon. domain.com:80,90,800-810;ip:80,90,800-810 6 Intranet Scan Blank, the IP address of your computer to use, the start and stop address of the last byte, or a combination of ip and range. (empty) or 192.168.0.191 or 100-199 or 192.168.0.191:100-199. 7 Intranet Scan (Sorted) Blank, the IP address of your computer to use, the start and stop address of the last byte, or a combination of ip and range. (empty) or 192.168.0.191 or 100-199 or 192.168.0.191:100-199. 8 Intranet Scan (Advanced) Blank, the IP address of your computer to use, the start and stop address of the last byte, or a combination of ip and range. (empty) or 192.168.0.191 or 100-199 or 192.168.0.191:100-199. 9 DNS Record A domain name. example.com 10 DNS Resolve A domain name or IP address. example.com or 126.96.36.199 11 DNS Resolve (Advanced) A domain name or IP address. example.com or 188.8.131.52 12 Whois (Domain) A domain name. example.com 13 Whois (Name Server) An IP address or domain name. 184.108.40.206 or example.com 14 Whois (Registrar) A business name. Network Solutions Credits: Global Whois (reference) by marschills Whois Resolver (reference) by Mentalis.org Dig.Net by Alphons van der Heijden Ping, ICMP, and Trace Route (reference) by jscott Version History: 1.0.0 - Used ping.exe and tracert.exe. 1.1.0 - Uses internal ICMP code for ping and trace route. 1.2.0 - Added DNS Resolve, DNS Resolve (Advanced) and Trace Route (Advanced). Changed the selection from radios to a combo box. 1.3.0 - Added DNS Record, Whois (Domain), Whois (Name Server), Whois (Registrar), and Port Scan. Also added a Stop button. 1.4.0 - Added Intranet Scan and Remote Port Scan. The application should be IPv6 capable now. Several other minor changes were made. 1.4.1 - Several minor fixes and improvements. 1.4.2 - Whois is more robust. Exception handling improved (not complete). Intranet Scan now only displays those that returned a name. 1.4.3 - Some code added to catch/prevent Intranet Scan errors. 1.4.4 - Changed the Intranet Scan code to not ping and get DNS info, just DNS info. Performance didn't change (DNS info has a long time out) although network chatter during a Intranet Scan should be greatly diminished. 1.4.5 - Made some changes to Remote Port Scan. It now attempts to establish a TCP connection with the port number. Remote Port Scan, therefore, won't work to test UDP connections. Also reenabled IPv6 on Intranet Scan. Unfortunately, an IPv6 scan will only detect other IPv6 computers on the intrenet. 1.4.6 - Added Clear Results button, it now displays the destination in both trace routes, and displays the version number in the title bar. 1.4.7 - Further improved the Intranet Scan. It is now approximately twice as fast as it was and gathers network devices regardless of whether or not they are named. 1.5.0 - Added Intranet Scan (Sorted). Tweeked a few settings in Trace Route (Advanced) and Intranet Scan. 1.5.1 - Several improvements made to both Trace Route actions. Universal timeout setting increased from 3 seconds to 5 seconds. 1.5.2 - Large chunks of Ping, TraceRoute, and Trace Route (Advanced) recoded. GUI reworked a bit. 1.5.3 - Intranet Scan and Intranet Scan (Sorted) now accepts "ip", "start-stop", and "ip:start-stop." Setting an IP allows you to scan one of the networks your computer is connected to (e.g. IPv4 or IPv6). Details in the table above. Also added Help -> Tech Power Up! 1.5.4 - Added WMI to Intranet Scans. 1.5.5 - Intranet Scan (Sorted) now shows the count of devices found before it outputs the sorted list. Cleaned up some code that would throw a NullReferenceException if conditions were right. 1.5.6 - Changed the appearance of Trace Route and Trace Route (Advanced) errors. 1.6.0 - Added tooltips and a guide under the Help menu. 1.6.1 - Intranet Scan and Intranet Scan (Advanced) now return OS Name if available. 1.7.0 - Added Intranet Scan (Advanced). Standardized the calculations for millisecond and seconds--they won't mess up if there was more than 999 milliseconds or 59 seconds. Seconds also shows milliseconds in decimal form.
