Network Intelligence
The network data shown here is also available via the Netify Data Feed API. We provide network intelligence to help deliver better digital experiences to end users and businesses.
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.Platform Domains

Some applications are deployed across network blocks. Only networks that are dedicated to an application are provided.
GitHub Network
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 active IP addresses on the GitHub Network.

SaaS for 3rd Party Applications
GitHub is a software-as-a-service (SaaS) platform used by third-party applications. You can find more information on the infrastructure used to deliver these services on the GitHub SaaS page.
Hosting
Cloud hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by GitHub 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.
