Does outbound traffic have a stable public IP?

Yes. Outbound traffic from your Pods leaves the cluster through a NAT that uses a documented set of public IP ranges per Availability Zone. Use those ranges when allowlisting CoreWeave-originated traffic in external services such as MongoDB Atlas, partner APIs, or firewalled databases. The current NAT Egress ranges for each AZ are listed in the Network information table on each region page. See Regions and Availability Zones for an overview, or go directly to a specific region:

US-EAST
US-CENTRAL
US-WEST
CA-EAST
EU-NORTH
EU-SOUTH
EU-WEST
