Some applications are deployed across network blocks. Only networks that are dedicated to an application are provided.

USPS 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 USPS Network.

Hosting

Hosting vendors like AWS and Microsoft Azure provide cloud-based computing and network resources to deliver applications. The hosting platforms used by USPS are summarized below by geographical points-of-presence (PoP).

Each PoP can host many IPs to deliver an application. A sample IP is provided.

Cloud Hosts	# of IPs
Amazon AWS	8

Hosting Platform	Network	PoP	Location	Sample IP	IPs
Amazon AWS	Amazon AWS	AWS GovCloud (US-West)	United States	52.61.128.40	8 IPs

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.

CDNs	# of IPs
Amazon CloudFront	2
Akamai	15
Edgio	13
