1. API Description

Domain name for API request: vpc.tencentcloudapi.com.

This API (AssignIpv6SubnetCidrBlock) is used to assign IPv6 subnet IP ranges.

  • To assign an IPv6 IP range to a subnet, the VPC that the subnet belongs to should have obtained the IPv6 IP range. If this has not been assigned, use the AssignIpv6CidrBlock API to assign an IPv6 IP range to the VPC to which the subnet belongs. Otherwise, the IPv6 subnet IP range cannot be assigned.
  • Each subnet can only be assigned one IPv6 IP range.

A maximum of 20 requests can be initiated per second for this API.

We recommend you to use API Explorer
Try it
API Explorer provides a range of capabilities, including online call, signature authentication, SDK code generation, and API quick search. It enables you to view the request, response, and auto-generated examples.
