AssignIpv6SubnetCidrBlock

Last Updated At: 2026-08-02 00:06:20

1. Interface Description

Interface request domain name: vpc.api3.convergecloud.com.

This API (AssignIpv6SubnetCidrBlock) is used to allocate IPv6 ranges.

  • To allocate an IPv6 range to a subnet, the subnet's VPC must have obtained an IPv6 range. If it is not allocated, allocate an IPv6 range to the subnet's VPC using the AssignIpv6CidrBlock API first. Otherwise, the IPv6 range would be unable to be allocated.
  • Each subnet can be allocated only one IPv6 range.

Default interface request rate limit: 20 times per second.

Interface update time: 2025-04-28 21:40:06.

The interface only verifies the signature but does not authenticate.
