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.
