The reason for writing this tutorial is that I recently moved a home for the website domain name. Because I reset the DNS server and resolution of the domain name, users in some regions who did not refresh DNS in time could not access my website.

For the latest resolution, the DNS cache time (TTL) I set is one hour, but some users have not been updated in time due to the server cache. In this case, you can manually update the server DNS settings to make them take effect. In view of the pagoda panel used by most webmaster friends, this tutorial takes pagoda as an example.

Note: It is not necessary to update manually. When the server cache time is up, it will be updated automatically. This depends on the server cache time.

1. Search the "Linux Toolbox" in the pagoda software store and install it directly after finding it

2. After installation, open the setting interface of the toolbox and find the DNS settings

Note: If you don't know how to find the DNS service, please keep it consistent with my screenshot.

3. After setting the DNS service, click Save on the right, and then click Test, as shown in the following figure

After completing the above steps, you can open the terminal on the left side of the pagoda, log in to your SSH account, and then enter “ping iddahe.com” When testing, the following screenshots will normally appear (optional here).

If it still cannot be solved, please contact me.
