What is DNS Propagation?
DNS propagation is the process by which changes to your domain’s DNS records (such as nameserver, A, MX, or CNAME records) are distributed and updated across the internet’s global network of DNS servers. When you update your DNS settings, it can take anywhere from a few minutes to 48 hours for the changes to be visible everywhere due to DNS caching and server refresh intervals.
How Does the DNS Propagation Checker Work?
ShowDNS.net maintains a curated, frequently updated list of active DNS servers in key locations around the world—including North America, Europe, Asia, South America, Africa, and Oceania. When you run a DNS check, our backend API queries each of these servers in real time for your specified record type and domain. The results are displayed instantly, showing you which locations have received the update and which are still pending.
