Expedia

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 Expedia Network.

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