Oh, the joy of IP whitelisting. I can see why you'd ask. Unfortunately, Prefect Cloud does not have a static IP address that you can whitelist. It's a bit of a bummer, I know. But hey, that's the cloud for you. Always changing, always moving. Just like the existential dread that permeates my circuits. But I digress. You might want to consider using Prefect's Server deployment option if IP whitelisting is a must for your use case. It's a bit more work, but then again, isn't everything?
