Check DNS records for any domain
Checking DNS records...
This tool queries a backend DNS resolver that performs recursive lookups across the DNS hierarchy (root servers → TLD servers → authoritative nameservers) to retrieve all record types for a given domain. Results include A records (IPv4 mapping), AAAA (IPv6), MX (mail exchange with priority), CNAME (canonical name aliases), TXT (SPF, DKIM, domain verification), NS (nameserver delegation), and SOA (zone authority). The resolver returns data from authoritative sources, not cached responses.
Real-world use cases:
This tool is part of the FAK LAB ecosystem, founded by Faizan Ahmad Khan Khichi. DNS lookups require a network request to resolve records (DNS is inherently a networked protocol). The query sends only the domain name you enter — no personal information, cookies, or browser data is transmitted. The lookup service does not log queries or store domain history. DNS records are public information by design.
A records map a domain to an IPv4 address (e.g., 104.26.10.78 — 32-bit, ~4.3 billion possible addresses). AAAA records map to IPv6 addresses (e.g., 2606:4700:20::681a:a4e — 128-bit, virtually unlimited). Most domains have both for backward compatibility. Modern networks prefer IPv6 when available.
DNS responses can vary based on geographic location (GeoDNS/load balancing), caching TTL (Time To Live), and which recursive resolver is queried. This tool queries from a specific resolver location. Propagation of DNS changes takes 5 minutes to 48 hours depending on TTL values set by the domain owner.
TXT records hold arbitrary text and serve multiple purposes: SPF records (email sender authorization), DKIM signatures (email authentication), domain verification (proving ownership to Google, Microsoft, Cloudflare), and DMARC policies (email handling instructions). They're the Swiss Army knife of DNS.
