Port Scanner Tool
Check common ports (HTTP, HTTPS, DNS) on any target host and see which services are responding.
What Port Scanner Checks
- Port Discovery: Tests HTTP (80), HTTPS (443), and DNS (53) ports for open/closed status
- Service Identification: Identifies the service running on each tested port
- Security Notes: Flags common misconfigurations such as unencrypted HTTP being served
- DNS Resolution: Resolves the target hostname to an IP address before scanning
- Risk Labeling: Labels open ports with a basic risk level (Low, Medium)
Why Use Port Scanner?
This tool checks the most common web and DNS ports on any publicly reachable host. It is useful for quickly verifying whether a server is serving HTTP, HTTPS, or DNS. Note: this is not a full port scanner: it tests ports 80, 443, and 53 only.
