What is DNS Propagation?

DNS propagation is the time it takes for DNS changes to spread across all DNS servers worldwide. When you update your domain's DNS records, those changes don't appear instantly everywhere.

How long does it take?

Typically 24–72 hours, though many changes propagate within minutes. Your TTL value controls how long old records are cached.

DNS Record Types

• A Record — Maps domain to IPv4 address
• AAAA Record — Maps domain to IPv6 address
• CNAME — Alias pointing to another domain
• MX Record — Directs email to mail servers
• NS Record — Nameserver records
• TXT Record — SPF, DKIM, verification

Speed Up DNS Propagation

• Lower TTL to 300s before making changes
• Use Cloudflare or Google DNS as your provider
• Flush your local DNS cache after changes
• Wait full TTL before expecting global updates

Why are some locations showing old IPs?
