Question: Does SDC support IPv6?
Answer: Our Data Collector core language was done in Java and, consequently, supports IPv6. Since we’re on Java Stack, the IPv6 is mostly there for the core Data Collector pieces. For compatibility with Data Collector, it mainly depends on the source / target you want to connect whether it supports IPv6. Since SDC acts as a system integrator, for each stage, we would have to go through it and see if they are IPv6 compatible or not.
For example: Oracle DB has started to support IPv6 connectivity since 12c, therefore theoretically Data Collector should also support it.
Please note that there are some technologies (and versions) that don’t support IPv6. If the origin or destination doesn’t support it, we currently don't have plans to create workarounds or patches to allow it.
Besides that, communications between Data Collector and Control Hub / Platform are done using IPv4, so it should be visible between the engine and the Platform. This is important if you want to deploy the engine in a VPC that only contains IPv6 for Internet access.
*Note: We have no existing testings that cover this use case. During testing, if you do run into any issues regarding IPv6, please open a ticket with Support so we can address it.
