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 GitHub Network.

GitHub is a technology platform used by third-party applications. The following is a summary of the infrastructure used to deliver these services.

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. A sample IP is provided.

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.
