Dns

Perform DNS record lookups for any domain name. Supports all major record types: A (IPv4 address), AAAA (IPv6), MX (mail servers), CNAME (canonical name), TXT (text records including SPF/DKIM), NS (nameservers), and SOA (start of authority). Useful for domain troubleshooting tools, email deliverability checkers, DNS monitoring dashboards, and network administration utilities.

Perform a reverse DNS (PTR) lookup to find the hostname associated with an IP address. Takes an IP address and returns its registered hostname. Useful for identifying servers by IP, verifying email sender authenticity, security investigations, and network administration tasks where you need to resolve IPs back to domain names.

Check the SSL/TLS certificate status for any domain. Returns certificate validity, issuer, expiration date, days until expiry, certificate chain details, and protocol support. Useful for monitoring website security, building uptime dashboards that track certificate health, alerting systems that warn before certificates expire, and security audit tools. Checks are performed in real-time against the live server.

Look up WHOIS registration data for any domain name. Returns the domain registrar, creation date, expiration date, nameservers, registration status, and available registrant contact information. Useful for domain research tools, brand protection monitoring, checking domain availability and age, due diligence on websites, and building domain management dashboards.
