GLOBAL DNS CHECKER

Global DNS Checker

Enter a domain and select countries to compare DNS records and response times from probes around the world.

01

Enter a domain and DNS record to query

Select up to eight countries and run lookups from a probe in each country.

You can enter only the domain without https://. Do not enter private internal addresses or confidential information.

Enter a domain and select the lookup button.

DNS PROPAGATION GUIDE

Country DNS Lookup and Worldwide DNS Propagation Check

After changing a domain's name servers or IP address, old and new values may appear in different countries and networks while DNS caches refresh. This tool requests DNS lookups from real probes in your selected countries and compares record values, status, and response time on one screen.

How to run a country-level DNS lookup

  1. Enter the public domain you want to check.
  2. Choose an A, AAAA, CNAME, MX, NS, TXT, or SOA record.
  3. Add or remove up to eight countries to compare.
  4. Select Run country DNS lookup and compare the measurements.

Useful for

  • Check DNS propagation after connecting a domain or changing name servers
  • Compare country-level A and AAAA records after moving a website
  • Verify MX and TXT records after configuring email
  • Check CDN and location-based DNS response differences

Differences Between DNS Record Types

A, AAAA, and CNAME

An A record maps a domain to an IPv4 address, while AAAA maps it to IPv6. CNAME makes one domain an alias of another.

MX, NS, and TXT

MX specifies mail servers and NS specifies authoritative name servers. TXT stores text-based policies and verification data such as SPF, DKIM, and domain verification.

SOA and TTL

SOA contains core administrative information for a DNS zone. Each record's TTL determines how long recursive DNS servers cache the response and affects propagation time.

Public Measurement Network Notice

Your browser sends the lookup directly to the Globalping public measurement API. Created measurements and results are public and may generally remain available for up to six months, so do not enter private or sensitive hostnames. Results may be unavailable when a country has no active probe.

Frequently Asked Questions

What is a DNS propagation check?

It queries a domain's DNS records from probes in multiple countries to compare whether new settings have reached each region. Results may temporarily differ because of DNS caches and TTL values.

Why do DNS results differ between countries?

Internet providers and recursive DNS servers use different caches, while authoritative DNS servers or CDNs may return different values by location.

Which DNS record types can I check?

You can query A and AAAA records used for website addresses, CNAME aliases, MX mail servers, NS name servers, TXT verification and policy data, and SOA zone information.

Are lookup results stored permanently?

Congdy Coding does not separately store the domain or results. However, Globalping measurements used for the lookup are public and may generally remain available for up to six months under its service policy.

Can I enter a company domain or private address?

Because this tool uses a public measurement network, do not enter internal hostnames containing confidential information or addresses you do not want to disclose. Use only public domains that resolve normally on the internet.
