IETF has formally announced IPv6 to be the next standard of Internet Protocol to conquer IPv4 address exhaustion problem. At the same time, the newly risen technologies like Internet of Things (IoT) and AI are mostly built in a cloud native way and deployed in the cloud such as VPC (Virtual Private Cloud). Therefore, in order to support these technologies, VPC are supposed to provide IPv6 Internet connectivity. However, Internet Protocol transfer from IPv4 to IPv6 should deal with the complicated VPC networking architecture and ensure that Internet Protocol must be changed on the fly without the impact on the existing IPv4 services in VPC. To solve these challenges, in this paper the dual IP stack provisioning and resource management technologies for the VPC architecture is designed and implemented to fulfill the near-zero downtime VPC Internet Protocol transfer from the IPv4-only to IPv4/IPv6 dual stack and finally until IPv6-only networking.
