How to Check DNS Propagation
Domains & DNS · Self-help guide
DNS propagation is the time it takes for DNS changes to update across different networks. After changing nameservers or records, wait before assuming something is broken. You can check propagation using an online DNS checker or command-line tools. On Windows, open Command Prompt and run nslookup yourdomain.co.uk. On macOS or Linux, run dig yourdomain.co.uk or nslookup yourdomain.co.uk. Check the record type you changed, such as A, CNAME, MX, or TXT. If some locations show the old value and others show the new value, propagation is still in progress. Avoid making repeated changes while waiting, because that can make troubleshooting harder and may extend confusion for users.
