WebMD 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 IP addresses on the WebMD Network.
IP | ASN Description | ASN | Route | Location | Shared |
---|---|---|---|---|---|
207.231.204.56 | Webmd Inc. | AS46617 | 207.231.200.0/21 | United States | |
207.231.205.21 | Webmd Inc. | AS46617 | 207.231.200.0/21 | United States | |

SaaS - Software-as-a-Service
Applications often use various third party platforms for providing authentication, advertisements, customer tracking, cybersecurity, e-mail services and more. The Software-as-a-Service (SaaS) platforms used by WebMD are summarized below by geographical points-of-presence (PoP).
Each PoP can host many IPs to deliver an application. A sample IP is provided. Typically, the IP addresses on Software-as-a-Service platforms are shared by multiple applications.

Hosting
Hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by WebMD are summarized below by geographical points-of-presence (PoP).
Each PoP can host many IPs to deliver an application. A sample IP is provided.

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.
