Port Checker
Check specific ports by their category with a single click
Check for open common ports and verify port forwarding
Open Port Checker
Check your port status online with our open port checker. It will quickly scan and display which ports are available at the IP address or host name you entered.
What is Port Checker?
Port checker is a free online tool that checks the port status of your router, essential for testing port forwarding settings. Our open port checker lets you view your current public IP address and test the port you forwarded in your router.
A port checker is a network scanner that quickly finds open ports on a computer network. The tool quickly displays which ports are available to communicate.
How to Check Port Status (for UDP/TCP Port)?
Simply follow these steps to check the port status by using our tool
Enter the IP Address/Host Name
Either use the default network address shown in the box or enter any IP address (IPv4 or IPv6)/host name in the input box.
Select Port
Enter the port number you want to check. You can select bulk port checking by port type, or manually enter the ports using these [(80, 443) or (1-49)] methods.
Check Port Status
Now, click on the "check port" button to check open ports using our port checker. It tests all chosen ports and shows whether each is open, closed, or filtered.
What is Port Status?
The port status shows whether the application on a server is accepting requests or not.
Open port
It means the application or service is actively running and waiting to accept connections on that specific port number.
Close port
If a port is closed, it means the host is receiving the request, but no services are listening on that port. The host sends an unreachable response.
Filtered
Filtered means the port is not available or blocked by the firewall, ISP, or server.
Types of Port
The following are common types of ports to check for port status.
Server port
Web servers are logical endpoints for the network connections and facilitate data exchange between the web server and clients. Standard server ports are 80 (https), 443 (httpsS), 21 (FTP), 25 (SMTP), 53 (DNS), and 3306 (MySQL).
Game port
Game ports are logical communication endpoints that an online game uses to send and receive data. Ports help a computer to distinguish between different types of incoming traffic. Standard game port numbers are 3074 for Xbox Live, PlayStation Network 3478-3480, and Steam Client/Server 27015-27030.
Application Port
You can use our tool to check application ports, which are dedicated virtual ports to connect with computer applications. For example, Printer sharing 515, 631, Apple remote desktop 3282, Windows remote desktop 3389, Yahoo Instant Messenger 5050.
P2P port
P2P ports are peer-to-peer devices directly connected to each other rather than through a centralised network. Standard p2p ports are: USENET 119, Direct Connect 375 and 425, and BitTorrent 6881-6889.
Custom Port
Custom ports are dedicated, private ports assigned manually by the user for a specific application or service. Network admins use these port numbers to improve security and avoid service conflicts. Custom port ranges from 49152 to 65535.
Features of Our Port Checker
The following are useful features of the open port checker
Automatic IP detection
The open port checker is quite efficient in determining your computer's public IP address. There is no need to find the IP address separately.
Quick Port Status Detection
Our check port tool quickly detects multiple port statuses in a few seconds. The primary feature of our tool is to detect whether the port is open (actively listening), closed (port is accessible but not listening), or filtered (a firewall is preventing access).
Support Ipv4/Ipv6 address
The port checker lets the user know what services are actively listening or not. You can see the names of services running against a dedicated port. The tool lists down the port number along with the name of the application or service in tabular form to quickly see results.
Support TCP/UDP Protocols
Port checker can detect the port status and whether the protocol your network uses is TCP or UDP. It works on connection-oriented TCP and connectionless UDP protocols.
Version Scan
Our port check tool provides detailed information on which services are listening, the software name and its version. It lets the user know which software is running on the port, helping them spot outdated software. Like version scan shows port 443 is open and running Apache https Server version 2.4.41
Work on the Host Name
It also works with the router's hostname or its public IP address. You can also add the IPv6 address to check port status online.
No Login/ Signup
There is no need to create an account to check port status on the network with the help of our port checker. No signup or login required, simply add the IP address, select the port and press the scan button to check the port status.
Use Cases of Our Check Port Tool
Our online port checker is designed to test and analyze the status of network ports on a device, server or router. It is a must-have tool for network administrators, gamers, developers and the IT security team. Here are a few applications of the tool mentioned below:
Verify Port Forwarding
You can use the Port Checker to verify whether the router is actually forwarding the packet. With our tool, you can confirm that the port-forwarding rules are properly configured and that the device is reachable from the public internet.
For example, while hosting a Minecraft server on port 25565, you can use the port check tool to check whether the port is open and accessible.
Trouble Shoot Firewall issues
Firewalls are essential protocols for protecting networks, but they can block traffic if not correctly configured. A port checker detects if a firewall is blocking connections to a specific port. Our tool helps detect whether a local firewall, a router-level firewall, or an ISP-level firewall blocks a port.
Like remote desktop RDP on port 3389 is not working, our port checker helps to determine if it is a firewall or service causing the problem.
Check Service Availability
With our check port tool, you can confirm whether key services like https (80), httpsS (443), SSH (22), and RDP (3389) are actively listening or accessible. It is quite helpful before launching apps or websites. As before, launching a new website means ensuring port 80 is ready to handle traffic.
Test Network Configurations
Our tool lets you validate network and server setups. It is beneficial to ensure that NAT, VPN, or server configurations are functioning as expected. For example, if you have set up a custom application on port 9000, the port checker can help ensure external users can actually connect.
Detect ISP Restrictions
In a few countries, ISPs block specific ports by default. Port checker helps you identify these restrictions so you can choose another port. If port 80 is blocked, you can host your website on an alternate port, such as 8080, and use a redirect or a reverse proxy.
Increase Network Security
By regularly checking port status, you can see which ports are open, closed, or filtered. It reduces security risk and keeps your network safe. If you find the telnet port 23 is unintentionally open, you can close it to avoid vulnerabilities.

FAQs
What are the UCP/TCP ports?
These are two types of ports. TCP ports are more reliable, ordered, and provide error-free communication between applications. UDP ports offer faster but less reliable communication, suitable where speed matters.
Does this port check tool check my computer only?
By default, it checks your target IP address. It scans your router's public IP address (which is indirectly your computer's IP address). However, if you provide any other website or server IP address, this tool can check & find ports for it.
Is the Port Checker Safe to Use?
Yes, absolutely. Port checker scans your own public IP address. It does not steal data from your system. It only sends basic packets to check the system's connectivity status.
How many ports does a computer have?
There are 65536 port numbers used for different applications and services, ranging from 0 to 65535.
