eToolz includes some of the most important networking tools like NS-Lookup, Ping, TraceRoute and Whois. It allows also to check E-mail addresses (MX-Server) and to search/convert domain names showing DNS entries (A, PTR, NS, SOA). eToolz supports also international domain names.
Note: the application starts in German, but you can immediately focus the "Sprache / Language" option in the window.
