Comprehensive Domain Intelligence
Get a complete picture of any domain's infrastructure in seconds. This tool combines DNS record lookups with WHOIS registration data in a single, fast query — saving you from juggling multiple separate tools.
DNS Record Types Explained
- A / AAAA — Maps a domain to its IPv4 or IPv6 address. The most fundamental DNS record.
- MX — Mail Exchange records that direct email to the correct mail servers.
- NS — Name Server records that indicate which DNS servers are authoritative for the domain.
- TXT — Text records used for SPF, DKIM, domain verification, and other metadata.
- CNAME — Canonical Name records that alias one domain to another.
- SOA — Start of Authority records containing zone administration information.
- SRV — Service records for locating specific services (e.g., SIP, XMPP).
WHOIS via RDAP
This tool uses the modern RDAP (Registration Data Access Protocol) to retrieve structured domain registration data. RDAP is the IETF-standardized replacement for traditional WHOIS, offering better internationalization and structured JSON responses.
Use Cases
- DNS Propagation — Verify that DNS changes have taken effect globally
- Email Troubleshooting — Check MX and TXT (SPF/DKIM) records for deliverability
- Security Analysis — Investigate suspicious domains and check registration history
- Domain Research — Check expiration dates and registrar information
- Website Migration — Verify DNS configuration before and after migrations
