Using the DNS Propagation Checker

Written by Bouncy Admin
Updated this week

Bouncy includes a built-in DNS propagation checker that lets you verify whether your DNS records have propagated correctly. This tool queries Google's public DNS servers to give you a reliable, real-time view of your DNS configuration.

What is DNS Propagation?

When you add or change DNS records at your registrar, those changes don't take effect instantly across the entire internet. DNS resolvers around the world need to pick up the new records — this process is called DNS propagation and can take anywhere from a few minutes to 48 hours.

How to Access the Propagation Checker

  1. Go to Custom Domains in the sidebar

  2. Find the domain you want to check

  3. Click the Check DNS or propagation checker button next to your domain

What the Checker Shows

The propagation checker queries Google's DNS-over-HTTPS API and displays the results for your domain's records.

For Root Domains

The checker looks for:

  • A record — should resolve to 216.150.1.1

For Subdomains

The checker looks for:

  • CNAME record — should resolve to cname.vercel-dns.com

Interpreting the Results

Result

Meaning

Correct records found

Your DNS is configured properly. You can proceed with verification.

No records found

Your DNS changes haven't propagated yet, or the records weren't added correctly.

Wrong values

Records exist but point to the wrong destination. Check your DNS configuration.

Tips for Using the Checker

  • Check early, check often — you can run the checker as many times as you want while waiting for propagation

  • Don't panic if it's slow — some registrars take longer to propagate. Give it at least 30 minutes before troubleshooting

  • Compare with your registrar — if the checker shows no records but your registrar's DNS panel shows them, propagation is still in progress

  • Google DNS is authoritative — the checker uses Google's DNS servers (8.8.8.8), which are among the first to pick up changes. If Google DNS shows your records, most of the internet will too

When to Use the Checker

  • Right after adding DNS records — to monitor when propagation completes

  • Before clicking Verify — to confirm your records are live before attempting verification

  • When troubleshooting — to check whether a domain issue is DNS-related

  • After making DNS changes — to verify that updates have taken effect

Propagation is Complete But Verification Fails?

If the propagation checker shows your records are correct but the Verify button still fails:

  1. Wait a few more minutes — there can be a slight delay between propagation and verification

  2. Check that your TXT record is also set up correctly (the propagation checker focuses on A/CNAME records, but verification also requires the TXT record)

  3. Make sure there are no conflicting DNS records for the same hostname

  4. If using Cloudflare, confirm the proxy (orange cloud) is disabled
