Which mailserver is responsible for this domain? Is a domain reachable? Who owns a IP? Or you want trace back a route of a package? With the Java Net Tool you will find it out!

Main features:

  • Whois: With jNetTool-whois you find out who owns a domain or IP-address. Please enter a domain without "www" - for example "ventruba.com".
  • DNS-Lookup: With jNetTool-ns-lookup you find out the nameserver for a domain, or which is the ip for a domain (A-record) or which mailserver is responsible (MX-record).
  • Ping: A jNetTool-ping is "knocking at the door" of a computer. You will see if a computer is answering and how long will a package take.
  • Traceroute: Which way will a package take from you computer to the target and how long will it take itemized for each station - jNetTool-traceroute will tell you.
  • Portscan: jNetTool-portscan: Which service offers the computer? Please take care with this, some owner would misinterpret this as an attack! Use ownly if allowed from the owner!
  • IP-Calculator: This nice tool shows you the networkclass of an IP-address, or you can calculate subnets, how many hosts are in a subnet, and so on...
  • Network planning: The jnetool-networkplaningtool is not for real business, for the moment.
