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 Windows Update IP addresses on this type of network.
ASN Description | ASN | Route | Location | IP | Shared |
---|---|---|---|---|---|
Microsoft Corporation | AS8075 | 2a01:111:f000::/36 | Netherlands | 2a01:111:f100:9001::1761:91b4 |
Hosting
Hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by Windows Update 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.
