Frequently Asked Questions
How does DNS-over-HTTPS (DoH) work in this lookup tool?
The tool queries Cloudflare (1.1.1.1) and Google (8.8.8.8) encrypted JSON DoH endpoints directly from your browser, bypassing local ISP DNS poisoning and eavesdropping.
What are the primary DNS record types and what do they do?
A points to an IPv4 address, AAAA points to an IPv6 address, CNAME points to another domain alias, MX handles email routing, and TXT is used for SPF, DKIM, and site verification.
How long does global DNS propagation take after updating records?
DNS propagation depends on the record Time-To-Live (TTL) value. Changes typically propagate worldwide within 5 minutes to 24 hours as upstream recursive caches expire.
