To check the propagation of DNS records for a Plesk domain, you can use online tools that allow you to query DNS servers worldwide to see if they have updated with the latest DNS information. Here's a step-by-step guide:

1. Choose a DNS Propagation Checker:

   • There are several online tools available for checking DNS propagation. Some popular options include:
     • DNS Checker
     • WhatsMyDNS
     • MXToolBox

2. Access the DNS Propagation Checker:

   • Open your preferred DNS propagation checker in a web browser.

3. Enter Your Domain Name:

   • In the provided field, enter the domain name for which you want to check DNS propagation.

4. Select the DNS Record Type:

   • Choose the specific type of DNS record you want to check (e.g., A record, MX record, CNAME, etc.).

5. Choose DNS Servers to Query:

   • You can choose to query specific DNS servers located in different regions around the world. Many propagation checkers offer options to select from a list of commonly used servers.

6. Initiate the Check:

   • Click on the "Search" or "Check" button to initiate the DNS query.

7. Review Results:

   • The propagation checker will display a list of DNS servers and their responses. This will show whether the DNS records have propagated or if they are still using the old information.

8. Interpret Results:

   • If you see that most DNS servers have updated to the new records, this indicates that the DNS propagation is taking effect. However, if some servers still show the old information, it means propagation is not yet complete.

9. Check TTL (Time to Live):

   • Keep in mind that DNS records have a TTL value, which determines how long the information is cached by DNS servers. If you recently made changes, but the TTL is still active, it may take some time for all servers to update.

10. Wait and Verify:

    • DNS propagation may take up to 48 hours in some cases, although it often happens much faster. Continue to check the propagation status over time until you see consistent results.

Remember that DNS propagation can be influenced by various factors, including TTL settings, the quality and location of DNS servers, and network configurations. Always double-check your DNS records in your Plesk panel to ensure they are correctly configured.
