Advanced Port Scanner is a free but robust network open ports scanner developed by the famous remote controller Radmin's official site. It features professional yet user-friendly GUI, abundant features, as well as very fast scanning speed.

As a network or website administrator, most often we need know everything quite well about the LAN or even WAN our hosts lying in. For example: the name of each computer in local network, network card address, IP address, shared resource, open ports; look up WHOIS information such as domain name, host provider, DNS... about some website in detail. For these, IP-Tools can become a good assistant for our network/Internet management.
