See response headers and IP for a URL. Debug DNS and connectivity.
Fetch a URL and display response headers and optionally the resolving IP. Helps verify that the host header and backend are correct after DNS changes, and to see security or cache headers. Often used together with DNS Lookup when troubleshooting resolution or routing.
Headers confirm the server responded and what it sent (e.g. Server, X-Backend). IP confirms which host was reached.
Some tools show both. This one focuses on response. Use a full request builder to send custom requests.
Server-side fetches may log client IP. Check the tool's privacy note.
The tool fetches the URL you give (http or https). Certificate details may be in a separate SSL checker.
Load balancers, anycast, or CDNs can return different IPs per request or location. Both are valid.
