Usage Limits

Last updated: 2024-01-11 16:04:31

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.
Note: 
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.
