This topic describes how to purchase an Anti-DDoS Pro instance of the Profession mitigation plan, Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan, Anti-DDoS Premium instance of the Mainland China Acceleration (MCA) mitigation plan, and Anti-DDoS Premium instance of the Secure Mainland China Acceleration (Sec-MCA) mitigation plan.
Select an instance type
- If your servers are deployed in the Chinese mainland, you must purchase an Anti-DDoS Pro instance of the Profession mitigation plan.
Notice
- You cannot use Anti-DDoS Pro instances to protect the domains for which you do not complete Internet Content Provider (ICP) filing. Before you use an Anti-DDoS Pro instance to protect your website, you must complete ICP filing for the domain of your website.
- By default, an Anti-DDoS Pro instance uses IPv4 addresses to forward access requests.
If you require an instance to forward access requests by using IPv6 addresses, submit
a ticket or contact sales personnel.
If you use an instance to forward access requests from clients that use IPv6 addresses, the destination varies based on the methods that are used to add your services to Anti-DDoS Pro or Anti-DDoS Premium. If you add your services by using domains, the access requests are forwarded only to origin servers that use IPv4 addresses. If you add your services by using ports, the access requests can be forwarded to origin servers that use IPv4 addresses or IPv6 addresses.
- If your servers are deployed outside the Chinese mainland and your services are provided to users who reside outside the Chinese mainland, you must purchase an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan.
- If your servers are deployed outside the Chinese mainland and you purchase an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation
plan, your users in the Chinese mainland may encounter a high network latency. The average network latency is about 300 milliseconds.
We recommend that you use the following solution:
- If you need only to ensure stable and fast access for users in the Chinese mainland,
purchase an Anti-DDoS Premium instance of the Sec-MCA mitigation plan. This solution
is not applicable to China Mobile users in the Chinese mainland.
Note The Sec-MCA mitigation plan can be used to mitigate DDoS attacks and accelerate access. Therefore, you do not need to purchase an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan. For more information, see Configure Anti-DDoS Premium Sec-MCA.
- If the preceding solution cannot meet your requirements, we recommend that you purchase
both an Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan and
an Anti-DDoS Premium instance of the MCA mitigation plan. An Anti-DDoS Premium instance
of the MCA mitigation plan does not provide mitigation capabilities.
Note You must use Sec-Traffic Manager to configure network acceleration rules for the Anti-DDoS Premium instance. If no DDoS attacks are detected, the Anti-DDoS Premium instance of the MCA mitigation plan accelerates requests that are destined for protected services. If DDoS attacks are detected, the Anti-DDoS Premium instance of the Insurance or Unlimited mitigation plan protects the services against DDoS attacks. For more information, see Overview
- If you need only to ensure stable and fast access for users in the Chinese mainland,
purchase an Anti-DDoS Premium instance of the Sec-MCA mitigation plan. This solution
is not applicable to China Mobile users in the Chinese mainland.
Supported connections
