IPv6 public network communication does not support DDoS protection by default. DDoS (Distributed Denial of Service) protection is a specialized service designed to mitigate the impact of DDoS attacks, which can overwhelm a network or service with traffic from multiple sources.
For example, if a website is experiencing a DDoS attack, the traffic from the attackers can cause the site to become unavailable to legitimate users. Without DDoS protection, the site's infrastructure may not be able to handle the influx of traffic, leading to downtime.
To address this, cloud service providers offer DDoS protection services that can be enabled for IPv6 public network communications. These services typically include features such as traffic filtering, rate limiting, and automated mitigation to detect and respond to DDoS attacks in real-time.
In the context of cloud services, Tencent Cloud offers a comprehensive DDoS protection service called Anti-DDoS. This service provides protection for both IPv4 and IPv6 traffic, ensuring that your applications and services remain accessible even during DDoS attacks. By leveraging Tencent Cloud's Anti-DDoS service, you can enhance the security and reliability of your IPv6 public network communications.
