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 pingsUse cases for a port scanner online:
- Detecting system vulnerabilitiesIt helps pinpoint open ports that could be targeted by attackers, assisting in the identification of critical security vulnerabilities.
- Analyzing active servicesThe scanner assesses running services and applications, providing a detailed review of their security configurations.
- Evaluating network connection securityScanning ports can determine the robustness of the security measures protecting your device's network connections.
- Identifying unusual network activityThe tool can detect unauthorized or inefficient use of network resources, signaling potential security breaches or misuse.
Which ports are scanned
The checker scans a variety of ports, including those utilized for essential services such as email (POP, POP3), data transfer (FTP), databases (SQL), and time synchronization (NTP). Identifying which ports are open, helps detect potential vulnerabilities and reduces the risks associated with unauthorized access.

How does a port scanner help improve network security?
A port scanner identifies the status of ports on a network, helping to detect and close unused or unprotected ports. This minimizes the risk of unauthorized access and mitigates potential network attacks.
Can I use your scanner to check my organization's network ports?
Yes, our scanner is aimed at evaluating organization network configurations, allowing administrators to identify open ports and potential vulnerabilities that could serve as entry points for attacks.
Which ports are considered the most vulnerable and are often checked?
Commonly checked ports include HTTP (port 80), HTTPS (port 443), FTP (port 21), and SSH (port 22), as these are frequently used for critical network functions and are common targets for attacks.
What information does a port scan display?
The scan results display the open or closed status of each port that has been scanned.
How often should I run a port scan to ensure security?
It is advisable to perform regular port scans as changes occur in your network infrastructure, when new services are deployed, or as new threats and vulnerabilities emerge.
Is it possible to identify which applications are using specific ports with your tool?
Our port scanner primarily checks the status of ports and does not provide details about the applications utilizing these ports. This type of analysis generally requires more advanced network monitoring tools.
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.
