1st Net Scanner is a comprehensive software that includes an IP Finder, Port Finder, IP Scanner, Port Scanner and IP Tracer. With its ability to scan and trace IP addresses, as well as find and scan ports, it is an effective tool for network administrators and security professionals.
One of the most significant benefits of using 1st Net Scanner is its ability to run three tests to determine whether a remote computer is still active. The ICMP, SYN, and UDP protocols are all available to test for computer vitality, while the CONNECT and SYN protocols are check for TCP ports that are under consideration.
In addition to these tests, 1st Net Scanner can reverse lookup an IP address into a hostname and read responses from all connected TCP Ports. The software assesses the UDP port's status based on the "ICMP Destination Port Unreachable" message. Users should limit port speed or the number of ports in use when first starting out, given the Linux kernel's destination unreachable message generation limitation.
As an added bonus, 1st Net Scanner also supplies all router information from the local host to the remote host. Whether you're using ICMP, SYN, or UDP, you can count on 1st Net Scanner to provide comprehensive and accurate information. Traceroute and ping use the same type, meaning you can rely on consistent results each time you get online.
