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.

Other Networks

There are tens of thousands of Internet network providers and we make an effort to track as many as we can, but we have less coverage for niche and local providers. The following is a sample of 3CX IP addresses on this type of network.

ASN Description	ASN	Route	Location	IP
Fusion Broadband	AS131476	43.245.170.0/24	Australia	43.245.170.90
Fusion Broadband	AS131476	103.4.237.0/24	Australia	103.4.237.181
Crystal Waters Fibre	AS142022	103.165.18.0/23	Australia	103.165.18.2
VMvault	AS56294	103.166.16.0/24	Australia	103.166.16.85
Exetel	AS10143	115.70.168.0/21	Australia	115.70.172.65

Hosting

Cloud hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by 3CX 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.
