Core Networks

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

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 Booking.com IP addresses on this type of network.

SaaS - Software-as-a-Service

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 Booking.com 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.

Hosting

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