Perimeter 81

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 Perimeter 81 Network.

Applications often use various third party platforms for providing authentication, advertising, cybersecurity, e-mail services and more. The Software-as-a-Service (SaaS) platforms used by Perimeter 81 are summarized below.

SaaS solutions are often deployed on multiple IPs across different geographical points-of-presence. In addition, it is common for these IP addresses to be shared by multiple applications.

Cloud hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by Perimeter 81 are summarized below by geographical points-of-presence (PoP). Each PoP can host many IPs to deliver an application.

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.
