Free DNS Propagation Checker

Check DNS records from multiple locations worldwide. Enter a domain name and select a record type to see how DNS has resolved across global server locations. Useful for verifying DNS changes after migration or updates.

How to Use the DNS Propagation Checker

  1. Enter a domain name — type the domain you want to check (e.g. example.com).
  2. Select record type — choose from A, AAAA, CNAME, MX, NS, TXT, or SOA.
  3. Click "Check DNS" — the tool queries DNS servers at multiple global locations and displays the results.
  4. Review the results — check the DNS records returned and see which locations have fully propagated.

Common DNS Record Types

A

IPv4 Address Record

Maps a domain name to a 32-bit IPv4 address (e.g. 192.0.2.1). The most fundamental DNS record type.

AAAA

IPv6 Address Record

Maps a domain name to a 128-bit IPv6 address. Used as the modern replacement for A records.

CNAME

Canonical Name Record

Aliases one domain to another. For example, www.example.com might be a CNAME pointing to example.com.

MX

Mail Exchange Record

Directs email to the mail servers for a domain. Includes a priority value — lower numbers are tried first.

NS

Nameserver Record

Specifies which DNS servers are authoritative for the domain.

TXT

Text Record

Stores arbitrary text data. Commonly used for SPF, DKIM, and DMARC email authentication.

SOA

Start of Authority Record

Contains administrative information about the domain, including primary nameserver and serial number.

Frequently Asked Questions

DNS propagation is the time it takes for DNS record changes to spread across all DNS servers worldwide. When you update a record, your authoritative nameserver immediately knows the new value, but cached copies on other servers may take time to expire and refresh.
Propagation time depends on the TTL (Time To Live) set on your DNS records. Typical TTL values range from 300 seconds (5 minutes) to 86400 seconds (24 hours). Global propagation is usually complete within 24-48 hours for most ISPs.
Before making DNS changes, lower your TTL to 300 seconds (5 minutes) at least 24 hours in advance. After propagation is complete, you can increase the TTL back to a higher value for better performance.
Different ISPs and DNS resolvers cache records for different durations. Some may respect your TTL exactly, while others may enforce minimum caching times. Flushing your local DNS cache may help.
Authoritative DNS servers hold the official records for a domain. Recursive DNS servers query authoritative servers on your behalf and cache the results.
