🔌 Port Lookup
Search the common TCP/UDP port reference database by port number or service name. This is a lookup tool, not a scanner — it never probes any live host.

How It Works
This tool searches a bundled reference database of well-known and commonly used TCP/UDP ports entirely in your browser — no network request is made, and no host is ever contacted or scanned. It's meant for quickly recalling what a given port is typically used for during troubleshooting or documentation.
Examples & Common Use Cases
- 22 → SSH
- 53 → DNS
- 443 → HTTPS
- 3389 → RDP
- Search "SQL" to find database-related ports like MySQL (3306) and MS SQL Server (1433).
