FixedmarkStatic IP use cases: allowlists, brokers, and partner APIs
You need a static outbound IP when the system you call only accepts traffic from addresses it has allowlisted: a stock broker's order API under SEBI rules, a bank payout API, a MongoDB Atlas cluster, or a partner's firewall. Serverless and PaaS platforms rotate egress IPs, so Fixedmark routes those calls through a dedicated, fixed pair.
