    Data Transmission Service:Add DTS server IP addresses to a whitelist

    Last Updated:Dec 18, 2025

    If your source or destination database uses a firewall or an IP address whitelist, you must add the IP address CIDR blocks of Data Transmission Service (DTS) servers to its security settings. This requirement applies to databases in on-premises data centers, from other cloud providers, or self-managed databases on ECS instances with strict security controls. Adding these IP addresses allows DTS to access your database and ensures that data transmission tasks can connect and run correctly.

    Introduction

    To connect to your database, DTS servers must be able to communicate with it over the network. For security purposes, databases often use access control policies, such as IP address whitelists, that reject requests from unknown IP addresses by default.

    When DTS connects to a database, its behavior is determined by the Access Method that you select:

    • Automatic Addition: If the source or destination database is an Alibaba Cloud database service, such as RDS, PolarDB, or MongoDB, and the Access Method is set to Alibaba Cloud Instance, DTS automatically adds the required IP address CIDR blocks to the database whitelist. No manual operations are required.

    • Manual Addition: If the database is connected using a method such as Public IP Address, Express Connect, VPN Gateway, or Smart Access Gateway, or Cloud Enterprise Network (CEN), you must manually add the IP address CIDR blocks of the DTS servers to the security settings of the database.

    Notes

    • IP address list source: The IP address CIDR blocks that appear in the authorization pop-up window in the console during task configuration may be outdated. We recommend that you use the IP address CIDR blocks provided in this topic.

    • IP address changes: The IP address CIDR blocks of DTS servers may be updated. When you first use DTS or receive a notification about a whitelist expansion, update your settings based on the information in the console or notification. We also recommend that you periodically check and update the IP addresses.

    • Add the complete IP address list: Make sure to add all the required IP address CIDR blocks for the relevant region. DTS service nodes may switch over for disaster recovery. If the IP address list is incomplete, the task is interrupted after a switchover.

      Note

      If your database is a cluster deployment, such as Kafka, Redis, or Doris, make sure to add the DTS IP address whitelist to the security settings of every server in the cluster.

    • Automatically added whitelists: Do not use whitelists that are automatically created by DTS for non-DTS services. The names of these whitelists usually contain dts or DTS. DTS may change these whitelists at any time. If you use them for other services, your business may be interrupted.

    • Security risks:

      • Adding the public IP address CIDR blocks of the DTS service, whether automatically by DTS or manually by you, can pose security risks. Using this product, you acknowledge the potential security risks and are required to implement basic security protection measures. These measures include but are not limited to strengthening account password protection, restricting open ports for each CIDR block, using authentication for communication between internal APIs, and regularly checking for and restricting unnecessary CIDR blocks. Alternatively, you can connect over a private network using an Express Connect, VPN Gateway, or Smart Access Gateway.

      • After a DTS task ends or is released, you must remove the added DTS IP address CIDR blocks from your security settings to protect your database.

    Step 1: Confirm the connection type

    Use the following table to determine the scenario and the required operation. If the connection method does not require manual configuration, except in special cases, or does not require you to manually add the DTS server IP address CIDR blocks, you can skip to What to do next.

    Connection type

    Scenarios

    Manual configuration required

    Description

    Alibaba Cloud Instance

    Alibaba Cloud databases such as ApsaraDB RDS, PolarDB, and MongoDB.

    No (except in special cases)

    The system automatically adds the DTS IP addresses to the database whitelist. Exceptions: MaxCompute and OceanBase require manual configuration. Cross-border or cross-region migration tasks also have special requirements.

    Self-managed Database on ECS

    A database deployed on an Alibaba Cloud ECS instance.

    No (except for clusters)

    The system automatically adds the DTS IP addresses to the ECS security group. Exception: If your database (such as Kafka, Redis, or Doris) is a cluster deployed on multiple ECS instances, DTS automatically configures the security group for only the first connected node. In this case, you must manually add the other ECS instances in the cluster to the security group created by DTS.

    Public IP Address

    • On-premises database

    • Database from another cloud provider

    • Database with a public IP address

    Yes

    You must manually add the IP address CIDR blocks of the DTS service for the corresponding region to the database's security settings.

    Express Connect, VPN Gateway, or Smart Access Gateway

    An on-premises database connected through an Express Connect circuit or VPN.

    Cloud Enterprise Network (CEN)

    An on-premises database connected through CEN.

    Database Gateway

    A database connected through Database Gateway.

    Yes (configure gateway IP)

    Unlike other methods, in this scenario, you do not need to add the IP address segments of the DTS service. You only need to add the IP addresses of all Gateway node ID in Database Gateway (DG) to the security settings of the database.

    Step 2: Determine the region for which to add IP addresses

    Use the following table to determine which database requires whitelisting and which region's DTS server IP addresses to add, based on your task type and database location.

    Task type

    Database to whitelist

    Region of the DTS server IP addresses

    Data synchronization

    Source database

    Regions of the source and destination databases

    Destination database

    Region of the destination database

    Data migration

    Source database

    Region of the destination database

    Destination database

    Region of the destination database

    Change tracking

    Source database

    Region of the source database

    Data validation (configured as a separate task)

    Source database

    Region of the destination database

    Destination database

    Region of the destination database

    Data Preparation

    Source database

    Region of the destination database

    Destination database

    Region of the destination database

    For example, when you prepare to migrate a self-managed MySQL database to an RDS for MySQL instance, if you use the Public IP Address connection type, you must add the public IP address range of the DTS server for the region of the destination database (RDS for MySQL instance) to the source database (self-managed MySQL database).

    Step 3: Add the IP addresses

    (Automatic configuration) ApsaraDB instances and self-managed databases on ECS

    Scenarios

    • Alibaba Cloud Instance: Alibaba Cloud services such as RDS and PolarDB. This does not apply to migration tasks for MaxCompute or OceanBase, or cross-border or cross-region migration tasks.

    • Self-managed Database on ECS: A single-node self-managed database.

    Configuration details

    DTS automatically configures the whitelist or security group when it connects. For more information, see Names of whitelists automatically added by DTS.

    • Alibaba Cloud Instance: DTS automatically creates whitelist groups in a fixed format based on the product.

    • Self-managed Database on ECS: DTS automatically creates a security group named SG-DTS-GROUP-xxxx and applies it to the ECS instance.

    Click to view the names of whitelists automatically added by DTS

    DTS automatically adds an IP address whitelist to an Alibaba Cloud database instance when a connection is established, for example, when you click Test Connectivity and Proceed in the console. The following table lists the Alibaba Cloud database instances for which DTS can automatically create IP address whitelists and the names of the whitelists.

    Note

    • The IP address whitelists automatically added by DTS are for DTS use only. If you use them for non-DTS services, those services may be interrupted.

    • The names of IP address whitelists automatically added by DTS contain dts or DTS.

    Self-managed Database on ECS

    ECS instance

    SG-DTS-GROUP-****

    Special cases

    • Cluster deployment: If your database, such as Kafka, Redis, or Doris, is deployed on multiple ECS instances, DTS automatically configures the security group for only the first connected node. You must manually add the other ECS instances to the SG-DTS-GROUP-xxxx security group created by DTS.

    • MaxCompute, OceanBase, and cross-border or cross-region migration tasks:

    Public IP

    Scenarios

    • Self-managed MySQL database in an on-premises data center.

    • Database from another cloud provider.

    • Any database that exposes services through a public IP address.

    Configuration steps

    Important

    If the Access Method for the database is Public IP Address, you must add the IP address CIDR blocks of the DTS servers in the regions of the source and destination databases to the security settings of the database instance.

    1. Obtain the IP address list: In the DTS server IP address CIDR blocks table, obtain the public IP address CIDR blocks for the region determined in Step 2.

    2. Configure the firewall or whitelist: Add the obtained IP address CIDR blocks to the firewall of the server where the database is located or to the security group policy of your cloud provider. Open only the database service port, for example, 3306 for MySQL.

    Security recommendations

    • Principle of least privilege: Open only the necessary database ports to the DTS IP address CIDR blocks. We do not recommend opening access to 0.0.0.0/0.

    • Strong authentication: Use a dedicated database account with the least privilege and a strong password for DTS.

    • Encrypted transmission: Enable and enforce Secure Sockets Layer (SSL) encryption for database connections when possible.

    Express Connect, VPN Gateway, Smart Access Gateway, or CEN

    Scenario

    An on-premises data center connected to a VPC through an Alibaba Cloud Express Connect circuit, VPN Gateway, Smart Access Gateway, or Cloud Enterprise Network (CEN).

    Configuration steps

    1. Obtain the IP address list: In the DTS server IP address CIDR blocks table, obtain the Alibaba Cloud service CIDR blocks for the region determined in Step 2.

    2. Configure routing and firewalls:

      • Cloud Enterprise Network (CEN): In the CEN instance, configure the private IP address CIDR block that you obtained for DTS as a cloud service.

      • Express Connect, VPN Gateway, or Smart Access Gateway: Add the obtained DTS private IP address CIDR block to the Local CIDR Block of the IPsec-VPN connection.

      • On-premises database: On the firewall of your on-premises data center, configure a policy to allow traffic from the DTS internal IP address CIDR blocks to access the database.

    Note

    After you add the IP addresses, check the configuration of your database instance to see if any settings are restricting access from DTS. For example, check the following file parameters in your self-managed database:

    • MySQL: bind-address.

    • PostgreSQL: listen_addresses.

    • MongoDB: bindIp.

    • Kafka: listeners and advertised.listeners.

    • Redis: bind.

    What to do next

    For security purposes, after a DTS task is released, we recommend that you remove the corresponding DTS IP address CIDR blocks from your database whitelist or security group. You can directly delete the whitelist groups, such as rdsdts, or security groups, such as SG-DTS-GROUP-xxxx, that DTS created automatically.

    Appendix: DTS server IP address CIDR blocks

    Note

    • When an on-premises database connects to DTS through Cloud Enterprise Network (CEN) or an Express Connect, VPN Gateway, or Smart Access Gateway, the IP addresses of the added DTS servers are all from the Alibaba Cloud internal CIDR block, which are subnets of 100.64.0.0/10.

    • If DTS adds new servers and you do not promptly update the whitelist of your self-managed database, DTS may fail to connect to the database.

    Description

    Query the IP addresses of DTS servers

    Queries the IP addresses of DTS servers.

    FAQ

    Which port should I open for the DTS service IP address CIDR blocks?

    You should open the port that your database uses to provide services. For example, the default port for MySQL is 3306, and the default port for PostgreSQL is 5432.

    What should I do with the IP address whitelists after the DTS task is complete?

    For security purposes, after a DTS task is released, we recommend that you remove the corresponding DTS IP address CIDR blocks from your database whitelist or security group. You can directly delete the whitelist groups, such as rdsdts, or security groups, such as SG-DTS-GROUP-xxxx, that DTS created automatically.

    Why does the Public IP connection type require me to add IP addresses for both the source and destination regions?

    This is required only for data synchronization tasks. Synchronization tasks deploy worker nodes at both the source and destination to perform bidirectional heartbeats and data comparisons. This process ensures data consistency and the stability of the synchronization link. Other task types, such as migration and change tracking, follow the single-region rule.
