If for any reason, you have changed the main server hosting your website and its IP address has changed, you only need to go to the CDN panel, “DNS records” section, and change the registered IP address for your A record in the ArvanCloud user panel.
Also, if you have an SPF record defined for your domain, change the IP addresses set for it.
Be careful that if your server’s email address has also changed, edit the MX record registered for your domain and register the new IP address.
Note: In general, any record that mentions the previous IP address of the website’s main server should be edited and replaced with the new IP address of the website’s main server.
