Depending on the CPU and memory configuration, the number of Elastic Network Interface (ENI) that can be bound to a CVM and the number of private IPs that can be bound to a single network interface can vary greatly. The following table lists the private IP quotas for ENIs and single network interfaces.
Note:
- The number of private IPs bound to a single network interface only represents the upper limit of the quantity of private IPs that can be bound to the network interface, not the number of EIPs actually provided. The EIP quota of each account is provided according to the EIP usage limit.
- Although the number of ENIs represents the quantity of network interfaces that can be bound to the corresponding configuration server, a CVM under the same VPC can be bound to a maximum of 1,000 ENIs.
| Virtual Central Processing Core (vCPU) | Number of ENIs | IPv4 quota | IPv6 quota |
|---|---|---|---|
| 1 | 2 | 6 | 6 |
| [2,4] | 4 | 10 | 10 |
| [6,8] | 6 | 20 | 20 |
| 12 | 8 | 30 | 30 |
| [14,64) | 8 | 40 | 40 |
| ≥64 | 16 | 40 | 40 |
Note:
- For details on CVM models, see Instance Specifications.
- BMS supports 32 ENIs, each of which supports 20 secondary private IP addresses.
