Cloud Sites IP Addresses for Whitelisting
When you are using the Cloud Sites platform, a third-party vendor might require an outbound IP address in order to add your domain to their safe list. Because sites do not get a dedicated IP address by default, you must provide the vendor with a list of potential outbound IP addresses. The outbound IP addresses you provide depend on the data center where your site data is stored. To determine which data center your site is in, view the test URL for your site in your Cloud Sites control panel.
