This topic describes best practices for purchasing and using elastic IP addresses (EIPs) integrated with Anti-DDoS Pro/Premium. You can purchase an EIP integrated with Anti-DDoS Pro/Premium and associate the EIP with a bandwidth plan that supports Anti-DDoS Pro/Premium to mitigate DDoS attacks. Compared with Anti-DDoS Origin Basic, Anti-DDoS Pro/Premium provides better security protection.

Limits on using EIPs integrated with Anti-DDoS Origin Basic

By default, Anti-DDoS Origin Basic can mitigate up to 5 Gbit/s of DDoS attacks. To meet higher security requirements, you can purchase EIPs integrated with Anti-DDoS Pro/Premium.

Traffic destined for origin servers is forwarded to the IP addresses of Anti-DDoS instances based on the forwarding rules that you configure. Traffic from the Internet is preferentially forwarded to data centers where traffic is scrubbed and malicious requests are blocked. Then, non-malicious requests are returned to origin servers by using port forwarding. This prevents malicious requests from accessing origin servers. In this scenario, the availability of the origin servers is ensured. However, you must change the IP addresses that are used to provide services. For more information, see What are Anti-DDoS Pro and Anti-DDoS Premium?.

Descriptions of EIPs integrated with Anti-DDoS Pro/Premium

To purchase an EIP integrated with Anti-DDoS Pro/Premium, select Anti-DDoS (Enhanced Edition) on the buy page. Anti-DDoS Pro/Premium can mitigate DDoS attacks at the Tbit/s level.

When you use EIPs integrated with Anti-DDoS Pro/Premium, you do not need to perform additional configurations or change the IP addresses that are used to provide services. EIPs integrated with Anti-DDoS Pro/Premium are suitable for scenarios where high security and low network latency are required, such as massively multiplayer online games and live streams.

How to use

After you purchase an EIP integrated with Anti-DDoS Pro/Premium, you must also purchase an EIP bandwidth plan that supports Anti-DDoS Pro/Premium and associate the EIP with the EIP bandwidth plan. Then, Anti-DDoS Pro/Premium can mitigate DDoS attacks at the Tbit/s level. How to use
The following steps describe the procedure of using an EIP integrated with Anti-DDoS Pro/Premium:
  1. Apply for the permissions to purchase an EIP integrated with Anti-DDoS Pro/Premium. Submit a ticket.
  2. Purchase an EIP integrated with Anti-DDoS Pro/Premium. For more information, see Apply for a new EIP. Purchase an EIP integrated with Anti-DDoS Pro/Premium
  3. Purchase an EIP bandwidth that supports Anti-DDoS Pro/Premium. For more information, see Create an EIP bandwidth plan. Purchase an EIP bandwidth that supports Anti-DDoS Pro/Premium
  4. Associate the EIP with the EIP bandwidth plan. For more information, see Associate EIPs with an EIP bandwidth plan.

Billing

Only pay-as-you-go EIPs and pay-as-you-go EIP bandwidth plans support Anti-DDoS Pro/Premium. The security protection fees of EIPs include only Anti-DDoS protection fees while the security protection fees of EIP bandwidth plans include Anti-DDoS protection fees and data processing fees.

  • Anti-DDoS protection fees are calculated based on the following formula:Anti-DDoS protection fee = Unit price for Anti-DDoS protection (USD/hour) × Usage duration (hour)

    Usage duration refers to the time period from when an EIP is created to when it is released.
