Port scanner online

The tool is aimed at diagnosing the status of network ports. It allows you to determine open ports on a computer or server, which helps to assess potential vulnerabilities.

Test your port:

If the result is «Host seems down», then the firewall or router of the target is checked and the IP is blocking pings

The online port scanning tool displays a list of ports detected on a specific IP address or domain. Users have the flexibility to choose the type of scan, enabling targeted examination of various ports such as those used for servers, gaming, P2P networks, and various applications. Additionally, the tool offers an option to quickly analyze the standard ports used by the most popular services and applications.

How a port scanner works

A port scanner begins by verifying the availability of the target host on the network. Here’s the process it follows:

The port scanning tool attempts to connect to each port on the target device using methods such as TCP Scan, UDP Scan, or Stealth Scan.
It analyzes the responses to these connection attempts to determine the status of each port, identifying whether they are open or closed.
Upon detecting an open port, the scanner examines the service operating on it and identifies the version of the software running.
The scanner then presents a list of all detected ports along with their status.

The information gathered during the scanning process is used to optimize the network connection, enhancing overall security.
