Is it currently possible to restrict the source IPs that are allowed to access my confluent cloud cluster that uses public internet networking?
I am having the same question, please let us know if that feature is available in Cloud Confluent?
You can access the basic and standard clusters over the public internet. However, you won’t be able to whitelist IP addresses for public Confluent Cloud clusters.
Also, currently, ingress IPs are not static. The cloud infrastructure that is used by Confluent Cloud does not guarantee static IPs across cluster changes, DNS is used to provide a consistent address.
The underlying IPs may be stable for some period of time, but are subject to change at any time, so they should not be relied upon for any use.
