TCP Port Scanner — scan
Limited track record
How we rate this
Delivery health: unknown. Paid successes: 0. Paid failures: 0. Schema confidence: high.
Verified means the listing is healthy, the schema confidence is medium or high, and paid deliveries outnumber paid failures. Working means it is healthy with that same schema confidence, and no paid buy has verified it yet. Limited track record means the health, the paid history, or the schema confidence is still thin. Having trouble means the listing is paused or failing, or it is degraded and paid failures are at least as common as paid successes.
Give this API a hostname or IP address and it tries connecting to each port in your requested range.
More
For every port that answers it reports whether it is open or blocked, which service is likely running there (a web server, SSH), and what software version was detected. Saves you installing network tools, parsing command-line output, or writing socket loops. Only scan hosts you own or have permission to scan - this tool does not check that for you.
