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

    Last Updated:Dec 13, 2025

    When you use Data Transmission Service (DTS), you may need to add the IP address CIDR blocks of DTS servers to your database's security settings. This is required if your source or destination database is protected by a firewall or whitelist, such as an on-premises database, a database from another cloud provider, or a self-managed database on an ECS instance with strict security controls. This action grants DTS access to your database, ensuring that the data transmission task can connect to the database and function correctly.

    Feature overview

    To connect to your database, DTS requires a network path between the DTS servers and your database. For security, databases often use access control policies, such as IP whitelists, that deny access requests from unknown IP addresses by default.

    When DTS connects to a database, its behavior depends on the connection type that you select:

    • Automatic addition: When the source or destination database is an Alibaba Cloud database, such as RDS, PolarDB, or MongoDB, and the connection type is Cloud Instance, DTS automatically adds the required IP address CIDR blocks to the database's whitelist. You do not need to perform this action manually.

    • Manual addition: When the database is connected using a Public IP, Express Connect circuit/VPN Gateway/Smart Access Gateway, or Cloud Enterprise Network (CEN), you must manually add the DTS server IP address CIDR blocks to the database's security settings.

    Precautions

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IP address CIDR blocks that appear in the authorization pop-up window during task configuration in the console may be outdated.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

    • IP address changes: The DTS server IP address CIDR blocks are subject to change. When you first use DTS or receive a notification to update the whitelist, you must update your settings promptly as instructed in the console or notification. We also recommend that you periodically check and update the list.

      • Cloud Enterprise Network (CEN): Update the cloud service configuration in CEN.

      • Express Connect circuit/VPN Gateway/Smart Access Gateway: Update the Local Network in the IPsec-VPN connection.

      • On-premises database: Update the security settings of the database.

    • Add the complete IP list: Make sure to add all IP address 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, whose names usually contain dts or DTS, for non-DTS services. DTS may adjust these whitelists at any time, which could interrupt your services.

    • Security risks:

      • Adding the public IP address CIDR blocks of DTS servers, whether automatically or manually, can introduce security risks. Using this product, you acknowledge and accept these potential risks. You must implement basic security protection measures. These measures include but are not limited to using strong account passwords, restricting open ports for each CIDR block, using authentication for internal APIs, and periodically reviewing and restricting unnecessary CIDR blocks. You can also connect using a private network (Express Connect circuit/VPN Gateway/Smart Access Gateway).

      • After the DTS task is complete or released, we recommend that you remove the added DTS IP address CIDR blocks from your security settings to ensure database security.

    Step 1: Confirm the connection type

    Use the following table to determine your scenario and the required actions. If your connection method 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

    Cloud Instance

    Alibaba Cloud databases such as 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.

    Self-managed database on an ECS instance

    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 deployment on multiple ECS instances, DTS automatically configures the security group only for 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

    • 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 circuit/VPN Gateway/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 (DG)

    A database connected through Database Gateway.

    Yes (configure gateway IP)

    Unlike other methods, this scenario does not require adding the DTS server IP address CIDR blocks. You only need to add the IP addresses of all Gateway Node IDs in Database Gateway (DG) to the database's security settings.

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

    Use the following table to determine which database requires a whitelist and the region of the DTS server IP addresses to add based on your task type and database location.

    Task type

    Database to add to the whitelist

    Region of DTS server IPs

    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 (task configured separately)

    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, if you are migrating a self-managed MySQL database to an RDS for MySQL instance and you use the Public IP connection type, you must add the public IP address CIDR blocks of the DTS servers for the region of the destination database (RDS for MySQL instance) to the source database (self-managed MySQL).

    Step 3: Add the IP addresses

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

    Scenarios

    • Cloud Instance: Alibaba Cloud databases such as RDS and PolarDB (excluding MaxCompute and OceanBase).

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

    Configuration details

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

    • Cloud Instance: DTS automatically creates whitelist groups with a fixed format for different products.

    • Self-managed database on an ECS instance: 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

    When DTS connects to an Alibaba Cloud database (for example, when you click Test Connectivity and Proceed in the console), it automatically adds an IP whitelist to the Alibaba Cloud database instance. The following table lists the Alibaba Cloud database instances that support automatic addition and the names of the corresponding whitelists.

    Note

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

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

    Handling special cases

    Public IP

    Scenarios

    • On-premises database.

    • Database from another cloud provider.

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

    Procedure

    Important

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

    1. Obtain the IP list: In 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 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, such as 3306 for MySQL.

    Security recommendations

    • Principle of least privilege: Open only the necessary database ports to the DTS IP 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 whenever possible.

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

    Scenarios

    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).

    Procedure

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

    2. Configure routing and firewall:

    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 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, after the DTS task is released, we recommend that you remove the corresponding DTS IP address 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 address CIDR blocks

    Note

    • When a local database connects to DTS through CEN or a Leased Line, VPN Gateway, or Smart Access Gateway, the IP addresses for the DTS servers are from an internal Alibaba Cloud IP address range (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 may fail to connect to the database.

    Description

    Query the IP addresses of the DTS service

    Queries the IP addresses of the DTS servers.

    FAQ

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

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

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

    For security, after the DTS task is released, we recommend that you remove the corresponding DTS IP address 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 the IP addresses of both the source and destination regions?

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