ℹ️ About DNS Propagation

When you update a DNS record, the change doesn't happen everywhere instantly. Each resolver caches records for the duration of their TTL (Time To Live) value. This means different users around the world may see different results for hours or even days after a change.

  • A records — Maps a domain to an IPv4 address
  • AAAA records — Maps a domain to an IPv6 address
  • MX records — Mail server addresses for your domain
  • TXT records — Text data including SPF, DKIM, and DMARC
  • CNAME — Canonical name alias pointing to another hostname
  • NS records — Your domain's authoritative nameservers

To speed up propagation, lower your TTL before making changes. A TTL of 300 (5 minutes) means changes propagate in under an hour for most users.
