Use our free Port Scanner to check the status of ports on a given IP address or hostname. You can scan a specific range of ports (up to 70 at a time) or a list of common ports.Important: Performing port scans from a web server can be slow, resource-intensive, and may be blocked by firewalls or hosting providers due to security policies. This tool is intended for light diagnostic use. For comprehensive scanning, dedicated tools run from a more permissive environment are recommended. IP Address or Hostname Enter the IP address (IPv4 or IPv6) or hostname to scan.
