Secure Connect Data Center IPs

[dkins]

Hi,

Is there a published KB article detailing the Secure Connect DC IP addresses? We need to understand what Public IP addresses traffic will be coming from and hitting services like Microsoft 365.

Hi @dkins ,

I would reach out to your Cisco Partner and Cisco AM to verify.  I have found the following:

Cisco+ Secure Connect Data Center List - Cisco Meraki

These are the Global DC's for Umbrella but there must be some dual-hosting involved:

Global cloud network activity & data centers - Cisco Umbrella

There are two different questions here. 
1. Secure Connect DC IP addresses- We utilize the Umbrella DCs so we use the same public IP addresses as Umbrella when connecting via IPsec tunnels. You can see the Umbrella DCs and their IP addresses here. Note no all Umbrella DCs support Secure Connect, check the Secure Connect DC list here. 

2. The public IP that will be listed as the source when landing at a destination such as a SaaS application will be one of the IPs in the Umbrella ranges. 146.112.0.0/16, 155.190.0.0/16, 151.186.0.0/16. We are just launching Reserved IP as a function in Secure Connect which will allow a customer to purchase dedicated IP addresses, more details to come on the Reserved IP capabilities.
