Domains

Primary Domains

Primary Domains are owned and managed by the application vendor.

Platform Domains are often provided by hosting providers, content delivery networks, SaaS platforms and other third parties. It is important to identify these domains for DNS filters and hostname blocklists.

Hosting

Cloud hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by Customer.io are summarized below by geographical points-of-presence (PoP). Each PoP can host many IPs to deliver an application.

Content Delivery Networks - CDNs

In order to get information to end users more quickly, many applications are distributed from multiple geographical points-of-presence (PoPs) using Content Delivery Networks (CDNs). Each PoP can host many IPs to deliver an application. A sample IP is provided.

Take special note of CDNs that use Anycast technology. Anycast makes it possible to route a single IP address to a variety of different geographic locations. In other words, one global Anycast IP is hosted in multiple geographic locations.
