The maximum number of Elastic Network Interfaces (ENIs) that can be bound to a Cloud Virtual Machine (CVM) and the maximum number of private IP addresses allowed for a single ENI are significantly different and vary based on the CPU specifications. The quotas for ENIs and private IP addresses per ENI are shown in the table below. You can also refer to Use Limits for other products within the same Virtual Private Cloud (VPC).
Note:
The number of private IP addresses that can be bound to a single ENI only indicates the maximum number allowed, but does not guarantee that the Elastic IP (EIP) quota is provided based on this upper limit. For details about the EIP quota provided for your account, see Use Limits of EIP.
The number of ENIs indicates the maximum number of ENIs that can be bound to a CVM of the corresponding configuration. In the same VPC, up to 1,000 ENIs can be bound to all CVMs.

Note:
For details about CVM instance types, see Instance Specifications.
Only some instance types of Cloud Physical Machine (CPM) 2.0 support ENIs, such as Standard BMS5, Memory Optimized BMM5c, High I/O BMIA2, Big Data BMDA2, and Standard BMSA2.
Each instance type of CPM 2.0 supports 32 ENIs, and each ENI supports 20 secondary private IP addresses. For more information, see CPM 2.0 Instance Specifications.
