Whitelisting the CDP

What are the IP Addresses that the CDP uses for integrations?

The CDP is hosted on Amazon Web Services (AWS) cloud infrastructure. So if you want to whitelist HTTP(S) traffic coming from the CDP you need to whitelist the traffic coming from the NAT Gateways

NAT Gateways:
1a : Public IP - 18.195.119.162
1b : Public IP – 18.195.17.174
