Network & Webmaster Tools

DNS, IP, whois, HTTP headers, redirects, SSL, meta tags, and security lookups — live results, zero upload.

DNS Lookup (A, AAAA, MX, TXT, NS, CNAME, SOA)

Query live DNS records for any domain through DNS-over-HTTPS — all record types in one place.

Look up any IPv4/IPv6 address — or your own — with geolocation, ISP, ASN, and organization data.

Check domain registration: creation and expiry dates, registrar, status codes, and nameservers.

Fetch any URL and inspect its response status, content type, security headers, and caching directives.

Follow the full redirect chain of any URL and verify each hop's status code, order, and destination.

Extract title, description, Open Graph, and Twitter Card tags from any page and preview the social share card.

Measure round-trip response time to any domain or endpoint from your current connection.

Verify a site serves HTTPS successfully and view certificate availability and protocol signals.

Check URLs against Google Safe Browsing with your own API key — phishing, malware, and unsafe page detection.

Drop any file to see its true MIME type — as declared and as sniffed from magic bytes — plus size and details.

Find anyone's Gravatar profile image from an email address — with size variants and direct URLs.
