What is DNS?

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 identify each other. When you change DNS records, the updates need time to spread across all DNS servers globally—this is called DNS propagation.

Common DNS Record Types

  • A Record: Maps domain to IPv4 address
  • AAAA Record: Maps domain to IPv6 address
  • CNAME: Alias from one domain to another
  • MX Record: Directs email to mail servers
  • NS Record: Specifies authoritative name servers
  • TXT Record: Text records for SPF, DKIM, verification

Speeding Up Propagation

  • Lower TTL values before making changes
  • Clear local DNS cache (ipconfig /flushdns)
  • Use public DNS like Google (8.8.8.8) or Cloudflare (1.1.1.1)
  • Wait 24-48 hours for full global propagation

Frequently Asked Questions

What is DNS propagation?
DNS propagation is the time it takes for DNS changes to update across all DNS servers worldwide. When you change DNS records, it can take 24-48 hours for the changes to fully propagate globally.
How long does DNS propagation take?
DNS propagation typically takes 24-48 hours, but can be faster (1-4 hours) with low TTL values. Factors affecting propagation include TTL settings, ISP caching, and geographic location.
What DNS record types can I check?
This tool supports A (IPv4 address), AAAA (IPv6 address), CNAME (alias), MX (mail exchange), NS (name servers), TXT (text/SPF/DKIM), and SOA (start of authority) records.
Why do DNS results differ by location?
DNS results differ during propagation because DNS servers in different locations update at different rates. Some servers may have cached old records while others have the new data.
