Configure resource group network connectivity - DataWorks

Add the IP addresses of a resource group to your data source's IP allowlist to ensure network connectivity and prevent access failures. This topic provides the IP addresses for different types of resource groups and notes on configuring IP allowlists.

IP addresses for shared resource groups

Before you create an API in Data Service, configure your data source. To ensure connectivity between Data Service and your data source, add the IP addresses for the corresponding region from the following tables to your data source's IP allowlist.

Important

The IP CIDR blocks for shared resource groups may change due to underlying infrastructure scale-outs. For better resource isolation, network connectivity, disaster recovery, and high availability, we recommend that you use serverless resource groups.

Whitelist addresses

The IP addresses of DataWorks shared resource groups for Public Cloud and Finance Cloud in the China (Shanghai) region are scheduled to change on March 23, 2026. The following table lists the allowlist addresses for all regions effective before March 23, 2026.

IP addresses for exclusive resource groups for Data Service

Exclusive resource groups for Data Service can access data sources over the public network, Alibaba Cloud VPCs, and IDC networks. The following table describes how to configure network settings in each environment to ensure connectivity between the exclusive resource group and data sources.

Note

For more information about how to use exclusive resource groups for Data Service, see Use an exclusive resource group for Data Service. Exclusive resource groups for Data Service are supported only in the China (Shanghai) region.

Network environment of the data source	Network connectivity solution	Network connectivity configuration guide
The data source is accessible over the Internet.	The exclusive resource group for Data Service can connect to the data source directly.	Log on to the VPC console. In the left-side navigation pane, choose Public Network Access > Elastic IP Address. In the target region, click Create Elastic IP Address. Note For detailed steps on creating an EIP, see Create an EIP. The region of the EIP must be the same as the region of the exclusive resource group for Data Service. In the left-side navigation pane of the VPC console, choose NAT Gateway > Internet NAT Gateway. In the target region, click Create NAT Gateway. Note For detailed steps on creating a NAT gateway, see Create a NAT gateway. The region of the NAT gateway must be the same as the region of the exclusive resource group for Data Service. Click Management on the right side of the created NAT gateway instance to go to the instance details page. On the Associated EIP tab, click Associate EIP. In the dialog, select an existing EIP and the corresponding name, and then click Determine. On the SNAT Management tab, click Create SNAT Entry. Set SNAT Entry Granularity to vSwitch Granularity. Select the corresponding vSwitch from the Select vSwitch drop-down list, select the corresponding IP address from the Elastic IP Address drop-down list, enter a custom Entry Name, and then click OK. Note The vSwitch selected when you create the SNAT entry must be the same as the vSwitch of the exclusive resource group for Data Service. Copy the public IP address from the created SNAT entry and add it to the IP allowlist of your data source. For more information, see Configure an IP allowlist.
The data source is in the classic network.	Exclusive resource groups for Data Service do not support this scenario. Use a shared resource group for Data Service instead.	N/A
The data source is in a VPC - The data source and DataWorks are in the same region, same VPC, and same vSwitch.	The exclusive resource group for Data Service can connect to the data source.	Log on to the VPC console. In the left-side navigation pane, click vSwitch to go to the vSwitch list page. Find the vSwitch of the exclusive resource group for Data Service and copy the IPv4 CIDR block. Add the IPv4 CIDR block of the vSwitch to the IP allowlist of your data source.
The data source is in a VPC - The data source and DataWorks are in the same region, same VPC, but different vSwitches.	The exclusive resource group for Data Service can connect to the data source.
The data source is in a VPC - The data source and DataWorks are in the same region but different VPCs.	The exclusive resource group for Data Service can connect to the data source.	Log on to the VPC console. Create a VPN gateway, a customer gateway, an IPsec-VPN connection, configure VPN gateway routes, and test private network communication. For more information, see Connect a VPC to a data center. Add the vSwitch CIDR block of the exclusive resource group for Data Service to the IP allowlist of your data source. Note Create two sets of VPN gateways, customer gateways, and IPsec-VPN connections, all in the same region.
The data source is in a VPC - The data source and DataWorks are in different regions.	The exclusive resource group for Data Service can connect to the data source.	Log on to the CEN console. Create a CEN instance, attach network instances, purchase a bandwidth package, set cross-region bandwidth, and verify connectivity. For more information, see Connect VPCs in different regions or Connect a VPC to a data center. Add the vSwitch CIDR block of the exclusive resource group for Data Service to the IP allowlist of your data source.
The data source is in an IDC.	The exclusive resource group for Data Service can connect to the data source.	Use Express Connect and CEN to connect the VPC of the exclusive resource group for Data Service to the IDC where the data source resides. Add the vSwitch CIDR block of the exclusive resource group for Data Service to the IP allowlist of your data source.

Configure data source allowlists

To prevent access failures between DataWorks Data Service and your data source, add the IP addresses of the resource group to the data source allowlist based on your resource group type. The configuration varies by data source type.

Take Alibaba Cloud ApsaraDB RDS as an example. RDS supports two allowlist modes: general and enhanced security. The allowlist group you select when adding entries may affect network connectivity between Data Service and the database.

If RDS uses the general allowlist mode:
- The general allowlist mode does not differentiate between classic network and VPC allowlist groups.
- Shared resource groups for Data Service and exclusive resource groups for Data Service can use the same allowlist group.
  
  Note
  In the general allowlist mode, the configured IP addresses can be used to access the RDS instance over both the classic network and VPCs.
If RDS uses the enhanced security allowlist mode:
- The enhanced security mode differentiates between classic network and VPC allowlist groups.
  
  Note
  In the enhanced security mode, each allowlist group specifies a network isolation mode. IP addresses in a classic network allowlist group cannot access the RDS instance over a VPC, and vice versa.
- When the exclusive resource group for Data Service connects to the database through the VPC internal network, select a VPC allowlist group.
- When the shared resource group for Data Service accesses a VPC data source (for example, a VPC-connected RDS MySQL instance configured in instance mode), select a VPC allowlist group.
- When the Data Service resource group accesses the database through the public endpoint or classic network endpoint, select a classic network allowlist group.
If you switch the allowlist mode from general to enhanced security in the database:

RDS copies the general allowlist into two copies and places them in the classic network and VPC allowlist group types respectively.

Additional notes on configuring allowlists:

Configuring an allowlist does not affect the normal operation of your RDS instance.
The default IP allowlist group (default) cannot be deleted but can be cleared.
Do not modify or delete system-generated groups to avoid affecting related services. For example, ali_dms_group (the IP allowlist group for DMS) and hdm_security_ips (the IP allowlist group for DAS).

Note
We recommend that you create a separate allowlist group for DataWorks when configuring the allowlist in the database.
The default IP allowlist contains only 127.0.0.1, which denies access from all IP addresses.

For more information about RDS allowlist configuration, see Configure an IP allowlist for an ApsaraDB RDS instance. The configuration for other data source types is similar. Refer to the allowlist documentation for each data source to add the corresponding entries.
