QUERY

You may paste a bare domain or a full URL; only the hostname is queried.

DNS record type

No browser or device DNS settings are changed.

  3. 3Compare answers, TTL values, DNSSEC, and consensus.
Regional entries are location-aware DNS views using EDNS Client Subnet, not physical probes inside each city. Global entries use independent public resolvers.

Direct public DNS queries — The public domain and selected DNS record type are sent to a ProntoUso server so it can query fixed public DNS-over-HTTPS resolvers. No browser, device, network, or domain settings are accessed or changed, and the query details and responses are not stored.

What is DNS Propagation Checker?

ProntoUso's DNS Propagation Checker queries global recursive DNS resolvers and public providers (including Cloudflare, Google, and Quad9) for A, AAAA, CNAME, MX, TXT, and NS records. Displays IP responses, TTL values, DNSSEC validation, and regional consensus metrics.

UNDERSTAND THE TOOL

How to Check Global DNS Propagation and Troubleshoot Zones

Track DNS record propagation across multi-region resolver nodes worldwide and monitor consensus percentages after domain updates.

How DNS propagation works

When updating domain IP addresses or DNS records, recursive resolvers worldwide do not refresh instantly. Resolvers store previous answers in local cache until the TTL (Time to Live) expires. Complete propagation occurs as caches clear and query the authoritative name servers.

Supported DNS record types

Query essential record types: A (IPv4 addresses), AAAA (IPv6 addresses), CNAME (canonical name aliases), MX (mail servers), TXT (SPF, DKIM, and verification records), and NS (authoritative name servers).

Understanding consensus percentages

Consensus metrics measure agreement across checked resolver nodes. A 100% consensus indicates all global nodes return matching records, while lower percentages highlight ongoing DNS cache migration.

How to use

  • Enter your domain or subdomain (e.g., example.com or api.example.com).
  • Select the target record type (A, AAAA, CNAME, MX, TXT, NS).
  • Click 'Check propagation' to query global DNS nodes.
  • Inspect regional response tables, TTL values, DNSSEC status, and consensus percentages.

Direct public DNS queries

The public domain and selected DNS record type are sent to a ProntoUso server so it can query fixed public DNS-over-HTTPS resolvers. No browser, device, network, or domain settings are accessed or changed, and the query details and responses are not stored.

Frequently Asked Questions

How long does full DNS propagation take?

DNS propagation typically completes within a few minutes up to 48 hours. The duration depends primarily on the TTL (Time to Live) set on previous DNS records before changes were made.

Why does the tool show the new IP propagated while my device still opens the old server?

Local devices and Internet Service Providers (ISPs) maintain local DNS caches. If global consensus is 100% but your computer sees old records, flush your local OS DNS cache (e.g., 'ipconfig /flushdns' on Windows) or restart your router.

What does a DNS divergence status mean?

Divergence occurs when resolver nodes in different regions return different IP addresses or records. This is expected during active server migrations or when using GeoDNS traffic balancing.

Can I check SPF and DKIM verification TXT records?

Yes. Select 'TXT' in the record selector to view full TXT strings worldwide and verify DKIM keys or SPF policies.

Can I enter raw IP addresses as input?

No. The input field requires a domain name or subdomain (e.g., domain.com). To look up domains from IP addresses, use a Reverse DNS (PTR) tool.
