EY 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 active IP addresses on the EY Network.

EY use the third-party SaaS platforms shown here. These services typically manage authentication, advertising, cybersecurity, e-mail services and more.

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

SaaS	Sample IP	# of IPs
Amazon AWS	63.182.10.2	8
Lumen	4.28.60.103	2
Microsoft Azure	191.234.216.180	55
