How to Check DNS Propagation
DNS propagation is the process where updated DNS records spread to DNS servers worldwide. After changing your DNS records, changes can take up to 24-48 hours to propagate globally, depending on your TTL setting.
To check propagation: Enter your domain name above, select the record type (A, MX, NS, etc.), and click Check DNS. Each location shows a ✓ green checkmark if propagated, or ✗ red if not yet.
Pro tip: Before making DNS changes, lower your TTL to 300 seconds at least 24 hours in advance for faster propagation.
Frequently Asked Questions
DNS propagation is the time it takes for DNS changes to be updated and reflected across all DNS servers worldwide. When you update a DNS record, the change must spread to thousands of DNS servers around the globe, which typically takes 24-48 hours.
DNS propagation usually takes between 24-48 hours globally. The speed depends on the TTL (Time To Live) value set on your DNS records. A lower TTL means faster propagation.
A DNS A record maps a domain name to an IPv4 address. It is the most common DNS record type and used to point your domain to your web server IP address.
Use this tool! Enter your domain, select the record type (e.g. A), and click Check DNS. Green checkmarks mean the DNS has propagated. Red marks mean it has not yet.
TTL (Time To Live) is the duration in seconds that a DNS record is cached by resolvers. A TTL of 3600 means the record is cached for 1 hour. Lower TTL equals faster propagation but more DNS queries.
DNS propagation speed is affected by your TTL value, your DNS hosting provider speed, and intermediate caching by ISPs. Lower your TTL to 300 seconds before making changes to speed up future propagation.
An A record maps a domain to an IPv4 address. An AAAA record maps a domain to an IPv6 address. IPv6 is the newer protocol with a much larger address space.
DNSSEC adds cryptographic signatures to DNS records, allowing resolvers to verify responses have not been tampered with. When validated, this tool shows a lock icon.
Your IP address is a unique number that identifies your device on the internet. Click the My IP Address tab above to see your current IP, location, ISP, and other details.
DNS-over-HTTPS sends DNS queries over an encrypted HTTPS connection, preventing eavesdropping and manipulation by third parties. This tool uses DoH from Cloudflare, Google, and Quad9 for all lookups.
