Port Scanner

The port scanner will scan ports of a public domain or IP address and see if a connection can be established.



This tool looks for open ports and is helpful for making sure that your firewall rules are working properly. Perhaps you accidentally left MySQL open to the outside world, or accidentally forgot to open up HTTPS. The port scanner will let you know!

To start, enter an IP or domain.  By default, the ports below are scanned.  If you do not see the port you're looking for, you can add it into the input box that appears above the results.

Default ports scanned:
  • 21 - File Transfer Protocol (FTP)
  • 22 - Secure Shell (SSH)
  • 23 - Telnet
  • 25 -  Simple Mail Transfer (SMTP)
  • 69 - Trivial File Transfer (TFTP)
  • 80 - World Wide Web HTTP
  • 110 - Post Office Protocol - Version 3 (POP3)
  • 135 - DCE endpoint resolution (EPMAP)
  • 139 - NETBIOS Session Service
  • 143 - Internet Message Access Protocol (IMAP)
  • 389 - Lightweight Directory Access Protocol (LDAP)
  • 443 - HTTP protocol over TLS/SSL (HTTPS)
  • 1433 - Microsoft-SQL-Server
  • 2049 - Network File System (NFS)
  • 3306 - MySQL Database
  • 3389 - MS WBT Server
  • 5060 - SIP
  • 5432 - PostgreSQL Database
  • 8080 - HTTP Alternate
  • 8443 - HTTPS Alternate

NOTE: Since this tool runs from our servers, you cannot scan local networks. As long as the IP or host is publicly available, you can scan it.
