FAQ
What information does "What's My IP" reveal?
It shows your public IP address as seen by websites you visit, along with approximate geolocation, ISP, and whether you are behind a VPN or proxy. It does not reveal your exact physical address.
What DNS record types does the DNS Lookup tool show?
It queries A, AAAA, CNAME, MX, NS, TXT, and SOA records. This covers the most common use cases — checking where a domain points, verifying mail server config, and inspecting SPF/DKIM records.
How does the Redirect Checker work?
It follows the full redirect chain from the URL you enter, showing each hop with its HTTP status code (301, 302, 307, etc.) and destination. This is useful for debugging SEO redirect chains or verifying short links.
What can I learn from HTTP headers?
HTTP headers reveal a site's caching policy, security headers (HSTS, CSP, X-Frame-Options), server software, content type, and compression settings. The Headers Checker shows all response headers for any URL.
Does WHOIS show the actual owner of a domain?
It depends. Many domain owners use privacy protection services that hide personal details. WHOIS will always show the registrar, registration dates, expiration date, and name servers, but contact info may be redacted.
