Usage notes

You cannot repeatedly call the ModifyVpcAttribute operation to modify the name and description of a VPC within the specified period of time.
You can call the ModifyVpcAttribute operation to enable IPv6 for a VPC. However, you cannot modify the IPv6 CIDR block or IPv6 CIDR block type for a VPC that has IPv6 enabled.

Debugging

OpenAPI Explorer automatically calculates the signature value. For your convenience, we recommend that you call this operation in OpenAPI Explorer. OpenAPI Explorer dynamically generates the sample code of the operation for different SDKs.

Request parameters

Parameter	Type	Required	Example	Description
Action	String	Yes	ModifyVpcAttribute	The operation that you want to perform. Set the value to ModifyVpcAttribute.
VpcId	String	Yes	vpc-bp1qtbach57ywecf****	The ID of the VPC that you want to modify.
Description	String	No	This is my VPC.	The new description of the VPC. The description must be 1 to 256 characters in length, and cannot start with `http://` or `https://`.

CidrBlock	String	No	192.168.0.0/24	The new IPv4 CIDR block of the VPC. You can specify a larger or smaller IPv4 CIDR block than the IPv4 CIDR block of the VPC. The subnet mask must be 8 to 28 bits in length. If you specify a smaller IPv4 CIDR block and existing IP addresses do not fall within the CIDR block, the modification fails. Note Your services are not affected when you modify the VPC CIDR block.
RegionId	String	No	cn-hangzhou	The ID of the region where the VPC is deployed. You can call the DescribeRegions operation to query the most recent region list.
EnableIPv6	Boolean	No	false	Specifies whether to enable IPv6 CIDR blocks. Valid values: true false (default)
