CapabilitiesOutbound network
Fixed outgoing IP
Traffic leaves from a known IP address that other services can whitelist.
Who offers it
Part of Outbound network: egress, allowlists and static IP, which explains why it matters.
Fully: Runtime. With a catch: Blaxel and Modal. Not at all: E2B and Sandboxer.
A dedicated outbound address costs $5 per 30-day month.

The catch: Dedicated addresses are in a private preview you must ask to join, and can only be attached when a machine is created.
docs-confirmed “This feature is currently in private preview and is not intended for production use.” Source
The catch: Only Team and Enterprise plans get it, and each account can create one or three gateways holding up to five addresses each.
docs-confirmed “Team Plan users can create one Proxy and Enterprise users three Proxies. Each Proxy can have a maximum of five static IP addresses.” Source
- E2BNo
Note: There is no dedicated or fixed outbound address on any plan, including Enterprise.
docs-confirmed “there are no dedicated or static egress IP addresses on any plan (including Enterprise).” Source
Note: Outbound traffic shares the host machine's address with every other sandbox on it, so other services see one shared address.
docs-confirmed “Outbound traffic shares the node's IPv4 address and IPv6 /64 with the other sandboxes on that node” Source
