• IPv6 NAT64 CLB can only be created in three regions: Beijing, Shanghai, and Guangzhou.
• IPv6 NAT64 CLB does not support classic CLB.
• IPv6 NAT64 CLB does not support getting client IPs.
• IPv6 implementations are still at the preliminary stage across the internet, and SLA is not guaranteed. In case of access failure, please submit a ticket for assistance.

CLB supports creating IPv6 NAT64 CLB instances. Tencent Cloud will assign an IPv6 public IP address, i.e., VIP of the IPv6 edition, to an instance, and the VIP will forward requests from IPv6 clients to the real IPv4 CVM instance.

IPv6 NAT64 CLB Instance Overview

An IPv6 NAT64 CLB instance is a load balancer implemented based on the IPv6 NAT64 bridge technology. Through an IPv6 NAT64 CLB instance, real servers can be quickly accessed by IPv6 users without any IPv6 modification required.

IPv6 NAT64 CLB Architecture

The IPv6 NAT64 CLB architecture is as shown below.

When IPv6 NAT64 CLB is accessed from an IPv6 network, CLB can smoothly convert IPv6 addresses to IPv4 addresses to adapt to existing services and quickly implement IPv6 transformation.

IPv6 NAT64 CLB Advantages

Tencent Cloud IPv6 NAT64 CLB has the following advantages when helping your business quickly connect to IPv6:

• Quick connection: CLB enables connection to IPv6 in a matter of seconds and is available upon purchase.
• Smooth business transition: in order to smoothly transit your business to IPv6, you only need to transform the client with no modifications required for real servers. IPv6 NAT64 CLB supports access from IPv6 clients and converts IPv6 messages into IPv4 messages. IPv6 transition is imperceptible to applications on real servers, which still work in their original way.
• Ease of use: IPv6 NAT64 CLB is compatible with IPv4 CLB operation process and easy to use with no additional learning costs incurred.
