I am using a wordpress plugin to backup wp to dropbox but web-server service provider restricts outgoing connections from my website and can add only IP's to allow some destinations from my site.
Plugin is BackWPup and it seems to connect https://api-content.dropbox.com to upload the backup's to dropbox.
I would need to find out the IP address range that https://api-content.dropbox.com uses so that my web-server service provider can allow these IP's for outgoing traffic from my website.
