Querying VPCs

Function

After a VPC is created, you can call this API to query all information about the VPC, including the VPC name, ID, and CIDR block.

Constraints

This API is used to query all VPCs accessible to the tenant submitting the request. A maximum of 2000 records can be returned for each query. If the number of records exceeds 2000, the pagination marker will be returned.
