+
+:::info
+Custom private DNS is in **Private Preview**. Reach out to the [ClickHouse support team](https://clickhouse.com/support/program) to enable it for your service.
+:::
+
+AWS PrivateLink provides [managed private DNS](https://docs.aws.amazon.com/vpc/latest/privatelink/manage-dns-names.html)
+for VPC endpoint services with a verified domain. Some services require each consumer to manage DNS resolution in their own VPC, e.g., Confluent Cloud requires consumers to resolve broker hostnames to the PrivateLink endpoint.
+
+For these cases, ClickPipes supports attaching custom private DNS names to a reverse private
+endpoint. ClickPipes resolves these names to the endpoint's private addresses, so your data
+source can be reached by its own hostname over private connectivity.
+
+Custom private DNS complements managed private DNS — it doesn't replace it. If your
+PrivateLink service already provides private DNS names, you don't need custom names.
+
+Custom private DNS names are supported for the [VPC endpoint service](#vpc-endpoint-service)
+and [VPC resource](#vpc-resource) endpoint types. MSK multi-VPC provides managed private DNS
+out-of-the-box and doesn't support custom names.
+
+The following rules apply to custom private DNS names:
+
+- Exact names (`kafka.internal.example.com`) and wildcard names (`*.example.com`) are
+  supported. A wildcard matches a single DNS label — for example,
+  `*.abcde12345.us-east-1.aws.confluent.cloud` matches
+  `b0-lkc123.abcde12345.us-east-1.aws.confluent.cloud`.
+- Names must be unique across all reverse private endpoints of a ClickHouse service,
+  including overlaps between wildcard and exact names.
+- Names under reserved suffixes (e.g., `local`, `localhost`, `internal`, `corp`,
+  `private`) are rejected.
+
+To configure custom private DNS names:
+
+- In the ClickHouse Cloud console, fill in the `Custom private DNS name` field when
+  [creating a reverse private endpoint](#creating-clickpipe). The field is shown once the
+  feature is enabled for your service.
+- With [OpenAPI](https://clickhouse.com/docs/cloud/manage/api/swagger), set
+  `customPrivateDnsMappings` when creating a reverse private endpoint, or update an existing
+  endpoint with a `PATCH` request. Updates replace the full list of mappings; an empty list
+  removes all custom names.
+- With Terraform, use the
+  [`clickhouse_clickpipes_reverse_private_endpoint_custom_private_dns`](https://registry.terraform.io/providers/ClickHouse/clickhouse/latest/docs/resources/clickpipes_reverse_private_endpoint_custom_private_dns)
+  resource to manage mappings on an existing reverse private endpoint.
