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.

Core Networks

Applications are sometimes deployed on partner networks, parent company networks, or regional hosting providers. The following is a sample of 3CX IP addresses deployed on this type of network.

Network	PoP	Category	Location	Route
Telstra	Core Network	ISP/Telco	Australia	60.224.0.0/13
Superloop	Sydney	ISP/Telco	Australia	116.255.0.0/19

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.
