Check Port
Checking for open or closed ports from outside a network is a common task to ensure that the respective protocol can communicate with others using that same protocol.

Our multilingual check port tool makes it easy to validate whether a port is open or closed from one of our locations.

  • Enter the IP address of the device you want to check the port on.
    Our tool only supports the IP address and not the fully qualified domain name (FQDN).
  • Enter the port number that you want to check.
    Some often checked ports are 80 (http), 443 (SSL), 3389 (RDP), SQL (1433), and FTP (21).
  • Select one of our locations that you want to check the port from.
    We have locations in Florida, North Carolina, and Quebec.
  • Click the check port button. Your results will be displayed.
