NetLookup is a network scanner and analyzer for home users, IT admins and web designers. It finds every device on your network with name, vendor, model, services and open ports, and reads the DHCP leases from your own router to name the ones that hide. My Connection checks network, router, internet, DNS and HTTPS in five steps and tells you in plain words where a problem is. For deeper work, every diagnostic tool, mail and DNS check and admin client sits next to the scan.
