Network / IP

HTTP Header Checker

Inspect status code, redirect chain, response headers, and basic security headers.

What is HTTP Header Checker for?

HTTP Header Checker shows the real response from a URL, including status code, headers, redirects, and key security headers for website or API debugging.

Recommended workflow

  1. Enter the URL to inspect, including http or https.
  2. Review status code, returned headers, and redirects when present.
  3. Use the security header section to spot missing configuration.

How this tool works

Network tools normalize IP, CIDR, host, or URL input, then calculate ranges or inspect live response metadata. They are useful for checking routing assumptions, allowlists, response headers, redirects, and public network ownership.
