Usage Limits

Last updated: 2022-06-08 15:30:37

The maximum number of ENIs that can be bound to a CVM and the maximum number of private IPs allowed for a single ENI vary according to the CPU specification. See the table below for details. For information on the quota limits for other VPC products, see Quota Limit.


  • The number of private IPs bound to a single ENI indicates the maximum number allowed. The EIP quota is not provided based on this upper limit but based on EIP quota.
  • The number of ENIs indicates the number of ENIs that can be bound to a CVM instance, while each VPC supports up to 1,000 ENIs.
