SmartAssess.io Tools

Port Checker

Check whether a single TCP port appears open from the SmartAssess.io server to a public host, IP address, or domain.

Port checks are a quick connectivity test. Firewalls, rate limits, VPNs, hosting rules, or private network settings can affect the result.

This first version checks one TCP port at a time and does not run nmap or scan port ranges.

Single-Port Check

Tests exactly one TCP port per request for a focused result.

Plain Results

Shows open, closed, or timeout status with a short explanation.

No Paid APIs

Uses PHP networking functions only, with no database or paid services.

Domain Resolution

Resolves domains to an IP address before testing the selected port.
