Some organizations deploy all or parts of an application solution through their own infrastructure instead of third party hosting providers like AWS or Google Cloud Platform. The following is a sample of IP addresses on the Constant Contact Network.

Applications often use various third party platforms for providing authentication, advertisements, customer tracking, cybersecurity, e-mail services and more. The Software-as-a-Service (SaaS) platforms used by Constant Contact are summarized below by geographical points-of-presence (PoP).

Each PoP can host many IPs to deliver an application. A sample IP is provided. Typically, the IP addresses on Software-as-a-Service platforms are shared by multiple applications.
