NetToolset is a free-for-personal-use suite of network tools.

A straightforward interface organises the program's functions across eight tabs: Ping, Traceroute+, DNS Lookup, Reverse DNS, Blacklist Lookup, IP Whois, Domain Whois and Port Scan.

There's no great complexity to any of these areas. Typically you'll click a tab, enter a domain or IP address and click a button. The Ping function has the most configuration options, including Rounds, Reply Timeout, Time between rounds, Bytes and Reverse DNS.

One plus is that you're not restricted to entering a single host or IP address at a time. Specify something like site1.com,site2.net,site3.org in the Ping box and the program will ping each one in turn, then display the results for you to study. The program can also import your targets from the clipboard, or intelligently read them from text files (CSV, text, web pages, message headers, more).

Whatever you're scanning is saved in a History, making it easy to recall and reuse later.

NetToolset's results can then be copied to the clipboard or saved as an HTML report in "Full" or "Compact" formats.
