I created this video to show how to check DNS propagation quickly when you’ve updated nameservers or made DNS changes for a domain.

Any time you switch hosts, set up a CDN, or move your site, DNS changes can take a while to fully propagate. This tool helps you confirm if it’s working worldwide.

In the video, I show:

  1. Going to a DNS checker tool like whatsmydns.net
  2. Entering your domain and selecting record type (A, CNAME, etc.)
  3. Viewing results from global DNS servers
  4. Understanding what a cached vs. updated result looks like
  5. When to wait vs. when to troubleshoot

I also explain how propagation usually takes 5 minutes to 48 hours, depending on TTL settings and DNS provider speed.

Do you check propagation after every domain update, or wait and hope it resolves?
