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

    Last Updated:Jan 22, 2026

    When you use Data Transmission Service (DTS), if the source or destination database has security policies such as a firewall or whitelist, you must add the IP address CIDR blocks of DTS servers to its security settings. This is especially important for on-premises data centers, databases from other cloud vendors, or self-managed databases on ECS instances with strict security controls. This action grants DTS access to your database and ensures that data transmission tasks can connect to the source or destination database and run smoothly.

    When DTS connects to a database, the connection behavior depends on the Access Method 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 Alibaba Cloud Instance, DTS automatically adds the required IP address segments to the database whitelist. No manual operations are required.

    • Manually add the IP address CIDR blocks of the DTS servers to the security settings of the database if the database is accessed via Public IP Address, Express Connect, VPN Gateway, or Smart Access Gateway, or Cloud Enterprise Network (CEN).

    Notes

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The IP CIDR blocks that appear in the authorization pop-up window during task configuration in the console may be outdated.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

    • IP address changes: The DTS server IP CIDR blocks may be updated. When you first use DTS or receive a notification about changes to the whitelist, update the settings promptly as instructed in the console or SMS notification. We also recommend that you regularly check and update the settings.

    • Add the complete IP list: Make sure to add the complete list of IP CIDR blocks for the required region. DTS service nodes may switch over for disaster recovery. If the IP list is incomplete, the task may be 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 whitelist to the security settings of every server in the cluster.

    • Automatically added whitelists: Do not use whitelists automatically created by DTS (names usually contain dts or DTS) for non-DTS services. DTS may adjust these whitelists at any time. Using them for other purposes may interrupt your services.

    • Security risks:

      • Adding public IP address CIDR blocks to the DTS service, either automatically or manually, can introduce security risks. Using this product, you acknowledge these potential security risks and are responsible for implementing basic security protections. Such protections include strengthening account password security, restricting open ports for each CIDR block, using authentication for internal API communication, and periodically reviewing and restricting unnecessary CIDR blocks. Alternatively, you can connect over a private network using a Express Connect, VPN Gateway, or Smart Access Gateway.

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

    Step 1: Confirm the connection type

    Use the table below to identify your scenario and the required actions. If your connection method does not require you to manually add the DTS IP address CIDR blocks (except in special cases), you can skip to What to do next.

    Connection Type

    Scenarios

    Manual Configuration Required?

    Description

    Alibaba Cloud Instance

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

    No (with exceptions)

    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 exceptions.

    Self-managed Database on ECS

    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 deployment on multiple ECS instances, DTS only configures the security group for the first connected node. In this case, you must manually add the other ECS instances to the security group created by DTS.

    Public IP Address

    • On-premises database

    • Database from another cloud vendor

    • Database with a public IP address

    Yes

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

    Express Connect, VPN Gateway, or Smart Access Gateway

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

    Cloud Enterprise Network (CEN)

    On-premises database connected through Cloud Enterprise Network.

    Database Gateway

    Database connected through Database Gateway.

    Yes (configure gateway IP)

    Unlike other methods, you do not need to add the IP address segments of the DTS service in this scenario. 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

    Based on your task type and database location, use the following table to determine which region's DTS server IP addresses you need to add to your database whitelist.

    Task Type

    Database to Whitelist

    Region of DTS Server IP

    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 (standalone job)

    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 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 CIDR blocks of DTS servers in the region of the destination database to the source database.

    Step 3: Add the IP addresses

    (Automatic configuration) Cloud instance/Self-managed database on ECS

    Scenarios

    • Alibaba Cloud Instance: An instance of an Alibaba Cloud service, such as RDS or PolarDB. This type does not apply to MaxCompute, OceanBase, or cross-border and cross-region migration tasks.

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

    Configuration details

    DTS automatically configures the whitelist or security group for you. For more information, see Whitelist names automatically added by DTS.

    • Alibaba Cloud Instance: DTS automatically creates whitelist groups in a predefined, product-specific format.

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

    Click to view the names of whitelists automatically added by DTS

    When DTS connects to an Alibaba Cloud database, it automatically adds its server IP addresses to the IP address whitelist of the database instance. For example, this occurs when you click Test Connectivity and Proceed in the console. The following table lists the Alibaba Cloud database instances and the names of the IP address whitelists that DTS can automatically create.

    Note

    • IP whitelists automatically added by DTS are for DTS use only. If you use them for non-DTS services, this may cause service interruptions.

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

    SG-DTS-GROUP-****

    Handling special cases

    • Cluster deployment: If your database, such as Kafka, Redis, or Doris, is deployed on multiple ECS instances, DTS configures the security group only for 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-region or cross-border migration tasks:

    Public IP

    Scenarios

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

    • Database from another cloud vendor.

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

    Configuration steps

    Important

    If the Access Method is set to Public IP Address, you must add the IP address segments of the DTS servers in the source and destination regions to the security settings of the corresponding database instances.

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

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

    Security recommendations

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

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

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

    Express Connect circuit/VPN Gateway/Smart Access Gateway/Cloud Enterprise Network (CEN)

    Scenarios

    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: From the DTS server IP address CIDR blocks table, retrieve the private IP address CIDR blocks for the IP region determined in Step 2.

    2. Configure routing and firewalls:

      • Cloud Enterprise Network (CEN): The private IP address segment for DTS is configured as a cloud service in the CEN instance.

      • Express Connect, VPN Gateway, or Smart Access Gateway: Add the DTS private network CIDR block to the IPsec-VPN connection's Local CIDR Block.

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

    Note

    After adding the IP addresses, check the configuration in your database instance for any settings that might restrict DTS access. For example, check the following configuration file parameters in self-managed databases:

    • 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 ends or is released, remove the corresponding DTS IP CIDR blocks from the 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 were automatically created by DTS.

    Appendix: DTS server IP CIDR blocks

    Note

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

    • When DTS adds new servers, if you do not promptly update the whitelist settings of your self-managed database, DTS connections to the database may fail.

    FAQ

    • Which port should be opened for the DTS service IP CIDR blocks?

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

    • What should I do with these IP whitelists after the DTS task is finished?

      For security purposes, after a DTS task ends or is released, remove the corresponding DTS IP CIDR blocks from the 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 were automatically created by DTS.

    • Why does the Public IP connection type require adding IP addresses from both the source and destination regions?

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