DNS Lookup
Query DNS records for any domain — A, AAAA, MX, TXT, NS, CNAME, SOA records via public DNS over HTTPS.
About DNS Lookup
DNS (Domain Name System) is the internet's phonebook — it translates human-readable domain names like example.com into IP addresses that computers use to communicate. Different record types serve different purposes: A records map domains to IPv4 addresses, AAAA to IPv6, MX to mail servers, TXT to verification tokens and SPF/DKIM records, NS to authoritative name servers, and CNAME to alias one domain to another. DNS lookups use the Google and Cloudflare public DNS over HTTPS (DoH) APIs, which provide fast, private, DNSSEC-validated responses.
FAQ
How long do DNS changes take to propagate?
DNS propagation time depends on the TTL (Time To Live) value of the record being changed. TTL is set by the domain owner — lower TTL (60-300 seconds) propagates changes faster, higher TTL (3600-86400 seconds) reduces DNS query load. After changing a record, old values can persist in caches for up to the previous TTL value — typically 1-48 hours for most domains.
