Explanation

Key technology: Security solution: Deploy security devices such as Anti-DDoS, internal and external network firewalls, IPS/IDS, etc., to ensure the security of the access area, and provide IPv6 security not less than IPv4 network capabilities. Load balancing design: Deploy GSLB/LLB to achieve global load balancing or link load balancing. Deploy SLB to implement load balancing on business servers. Internet egress design: Publish service routes through static routes or EBGP4+. DNS6 deployment solution: Create a new DNS6 server in the newly created DMZ zone, add AAAA records, and publish it to the public. Features: No impact on IPv4 services, the initial preferred solution. Advantages: It has no impact on IPv4 services, can quickly provide IPv6 services, and can smoothly evolve to the long-term goal of "network-wide single-stack" and accumulate IPv6 Operational experience, skills preparation in advance. Disadvantages: It is necessary to build a new Internet access area and DMZ area as a whole, and the investment is larger than that of NAT64, and the workload is moderate. Applicable scenarios: IPv6 evolution does not affect IPv4 services on the live network and does not allow service For example: a bank data center.
