DNS Lookup
Query authoritative DNS zones in real-time. Fetches IPv4 (A), IPv6 (AAAA), Canonical Name (CNAME), Text (TXT), and Nameserver (NS) records.
Frequently Asked Questions
A Canonical Name (CNAME) record maps an alias domain name (e.g. subdomain 'www.example.com') to an authoritative canonical domain name (e.g. root domain 'example.com'), routing requests directly to the master server.
Text (TXT) records hold arbitrary descriptive text strings. They are extensively used by systems to verify domain ownership (e.g. Google Search Console) and implement email security frameworks such as SPF, DKIM, and DMARC.
