Check DNS Propagation Across 24 Global Servers
A DNS Checker queries multiple geographically distributed DNS servers simultaneously to verify whether your DNS records have propagated worldwide. Unlike a simple DNS lookup that queries one resolver, this tool shows you the current state of your records across 24 servers spanning 6 continents—revealing inconsistencies, propagation delays, and regional differences in real-time.

Type your domain (e.g., example.com). No need for http:// or www prefix.
Select Record Type
Choose from 12 record types: A, AAAA, MX, CNAME, TXT, NS, SOA, PTR, CAA, SRV, DS, or DNSKEY.
Click Check
Click the Check button to query all 24 DNS servers simultaneously.
Watch Real-Time Results
See results appear progressively as each server responds. Fast servers (Google, Cloudflare) respond in 15-50ms.
Export or Enable Auto-Refresh
Download results as JSON, CSV, or TXT. Enable auto-refresh (10-300 seconds) to monitor propagation progress.
Understanding Your DNS Check Results
What each field tells you about DNS propagation status
Propagation Percentage
The percentage of servers that returned a consistent DNS record. 100% means all reachable servers have the same value—your DNS has fully propagated.
79% (19/24 servers)
Server Status Icons
Color-coded status: Green = Propagated (record found), Yellow = No record/NXDOMAIN, Orange = Query timed out, Red = Error. Each status helps diagnose propagation issues.
🟢 Propagated, 🟡 Not Found
Response Time
Round-trip latency in milliseconds for each server's DNS query. Typical times: US servers 15-60ms, EU 40-80ms, Asia 100-300ms, Africa/South America 200-500ms.
19ms, 87ms, 342ms
Resolved Value
The actual DNS record value returned by each server. For A records, this is an IP address. For MX, it's the mail server hostname with priority.
142.251.221.110
Consensus Value
The most common value returned across all servers. If this matches your expected value, propagation is on track. Multiple different values indicate propagation in progress.
93.184.216.34 (found on 19 servers)

When You Need DNS Propagation Checking
Common scenarios where DNS Checker helps
Website Migration
Moving to a new hosting provider? Check that your A record update is propagating globally before updating any other services. Monitor auto-refresh to confirm when the majority of traffic will route to your new server.
DNS Record Updates
Changed your CNAME for a CDN or updated your A record? Verify the change has propagated to all regions. Use expected value highlighting to quickly spot which servers still have the old record.
Email Configuration
Setting up email? Check MX record propagation to ensure mail routes correctly worldwide. Verify SPF/DKIM TXT records have propagated before sending emails to avoid deliverability issues.
SSL Certificate Validation
Certificate authorities require DNS validation via TXT or CNAME records. Check that your validation record has propagated globally before requesting the certificate.
Troubleshooting Access Issues
Users in specific regions can't reach your site? Check if DNS records are consistent in their region. Identify if the issue is propagation-related or something else entirely.
Monitoring DNS Changes
Enable auto-refresh after making DNS changes and watch propagation progress in real-time. Document the timeline for future reference or compliance.
How DNS Propagation Works
What is DNS Propagation?
When you update a DNS record, the change starts at your authoritative nameservers but doesn't instantly appear everywhere. DNS servers worldwide cache records based on TTL (Time To Live) values. Until each server's cache expires, it continues returning the old value. Propagation is the process of all caches updating with your new record.
Why Propagation Takes Time
Three factors control propagation speed: TTL value (lower = faster updates), ISP caching policies (some ISPs ignore TTL), and query patterns (frequently-accessed domains update faster). Typical propagation takes 15 minutes to 48 hours. You can reduce future propagation time by lowering TTL values 24-48 hours before planned changes.
Our Query Architecture
We query 24 DNS servers simultaneously using async parallel requests. Each server has a 3-second timeout. Results stream in real-time as servers respond—you see fast servers (Google, Cloudflare at 15-50ms) immediately while slower regional servers (Africa, South America at 200-500ms) update shortly after.
Server Distribution
Our 24 servers include major global resolvers (Google 8.8.8.8, Cloudflare 1.1.1.1, Quad9 9.9.9.9), regional providers (Yandex Russia, AliDNS China, Korea Telecom, TWNIC Taiwan), privacy-focused (AdGuard, UncensoredDNS), and enterprise (Neustar, Verisign). This diversity ensures you see how records appear across different network types and regions.

Frequently Asked Questions
What is DNS propagation?
DNS propagation is the time it takes for DNS record changes to spread across all DNS servers worldwide. When you update a record, caching servers must wait for their cached version to expire (based on TTL) before fetching the new value. This process typically takes 15 minutes to 48 hours.
How long does DNS propagation take?
Most DNS changes propagate within 1-4 hours for domains with standard TTL settings (3600 seconds). Lower TTL values mean faster propagation. Some ISPs have aggressive caching that may extend this to 24-48 hours regardless of TTL.
How many DNS servers do you check?
We query 24 public DNS servers distributed across 6 continents: North America (6 servers including Google, Cloudflare, Quad9), Europe (6), Asia (5), Oceania (3), South America (2), and Africa (2 including Kenya and South Africa).
Why do some servers show 'Query timed out'?
We use a 3-second timeout per server to ensure fast results. Some regional servers (particularly in Africa and South America) may be slower or experience connectivity issues. Timeouts are normal for 2-5 servers and don't indicate a problem with your DNS.
What DNS record types can I check?
12 record types: A (IPv4), AAAA (IPv6), MX (mail), CNAME (alias), TXT (text/verification), NS (nameserver), SOA (zone authority), PTR (reverse DNS), CAA (certificate authority), SRV (service), DS (DNSSEC delegation), and DNSKEY (DNSSEC key).
Can I speed up DNS propagation?
You cannot speed up current propagation—existing caches must expire naturally. However, you can reduce future propagation time by lowering TTL values (e.g., to 300 seconds) 24-48 hours before making changes. After the change, restore higher TTL values.
Why do different servers show different values?
During propagation, servers cached the record at different times. Those with older caches show the old value while those that recently refreshed show the new value. This is normal and resolves once all caches expire. Use our consensus value to see the most common result.
What does propagation percentage mean?
Propagation percentage shows what portion of our 24 servers return the same (consensus) DNS value. 100% means full propagation—all servers agree. Lower percentages indicate propagation is in progress or some servers have different cached values.
Can I export the DNS check results?
Yes, download results as JSON (for developers and APIs), CSV (for spreadsheets and analysis), or plain text (for documentation). You can also copy all results to clipboard with one click.
What is the CD flag (Checking Disabled)?
The CD (Checking Disabled) flag bypasses DNSSEC validation on the resolver side. Use this when debugging DNSSEC issues or checking records on domains with misconfigured DNSSEC. It's an advanced option for troubleshooting.
How does auto-refresh work?
Enable auto-refresh to automatically re-check DNS propagation at your chosen interval (10-300 seconds). This is perfect for monitoring propagation after making a DNS change—watch the percentage climb as more servers update.
What continents are covered?
All 6 inhabited continents: North America (6 servers), Europe (6), Asia (5), Oceania (3), South America (2), and Africa (2). We specifically include Africa (Kenya, South Africa) which many competitors miss.
Is this DNS checker free to use?
Yes, completely free with no account required. We also offer free API access for developers who want to integrate DNS checking into their workflows.
