Scan Commonly Running Ports on an IP or a Host Name


This free online tool from SolveDNS allows you to scan commonly used ports on an IP or a host name. This is useful for debugging potential service issues on your server by having a third party external server try to connect to your server on the respective ports. Having not used ports open is also a security risk as you might be unaware of who is connecting to your server on ports that you don't maintain or monitor.

We scan the following ports on the IP or host you enter:

  • HTTP port 80
  • HTTPS port 443
  • FTP port 21
  • SSH port 22
  • TELNET port 23
  • SMTP port 25
  • DNS port 53
  • POP3 port 110
  • FINGER port 79
