Frequently Asked Questions
What is DNS-over-HTTPS (DoH)?
DNS-over-HTTPS sends DNS queries over an encrypted HTTPS connection instead of plain UDP. Cloudflare's DoH API (1.1.1.1) is CORS-enabled, allowing DNS lookups directly from the browser without a backend proxy.
Why do my DNS changes not appear immediately?
DNS changes propagate based on the TTL (Time To Live) of the previous record. Low TTLs (60–300s) propagate in minutes; high TTLs (86400s = 24h) can take up to 48 hours globally.
