What is DNS propagation?

DNS propagation is the time it takes for DNS changes to update across all DNS servers worldwide. This typically takes 24-48 hours but can vary.

How does the DNS checker work?

Our DNS checker queries multiple DNS servers globally to show you the current DNS records and propagation status for any domain.

What DNS record types can I check?

You can check A, AAAA, MX, TXT, CNAME, NS, SOA, and PTR records. Each record type serves different purposes for domain configuration.

Why are DNS results different across servers?

DNS servers cache records for efficiency. During propagation, different servers may have different versions of records until fully updated.

How often should I check DNS propagation?

After making DNS changes, check every few hours. Most changes propagate within 4-8 hours, but allow up to 48 hours for global propagation.

Understanding DNS Records

Essential Record Types

A Record: Points domain to IPv4 address (e.g., 192.0.2.1)

AAAA Record: Points domain to IPv6 address

CNAME: Creates alias to another domain name

MX Record: Directs email to mail servers

TXT Record: Stores text data (SPF, DKIM, verification)

Advanced Record Types

NS Record: Delegates zone to nameservers

SOA Record: Start of Authority for the zone

CAA Record: Controls SSL certificate issuance

SRV Record: Specifies location of services

PTR Record: Reverse DNS lookup

DNS Best Practices

Use Multiple Nameservers

Always have at least 2-4 nameservers for redundancy

Set Appropriate TTLs

Use 300s for frequently changed records, 86400s for stable ones

Implement Email Authentication

Add SPF, DKIM, and DMARC records for email security

Enable DNSSEC

Add cryptographic security to prevent DNS spoofing

Monitor DNS Health

Regularly check for misconfigurations and issues

Document Changes

Keep records of DNS modifications and reasons
