An elastic IP address (EIP) is a public IP address that you can purchase and use as an independent resource.
EIPs support BGP (Multi-ISP) lines and BGP (Multi-ISP) Pro lines. The following table describes the differences between BGP (Multi-ISP) and BGP (Multi-ISP) Pro.
|Item||BGP (Multi-ISP)||BGP (Multi-ISP) Pro|
|Advantages||BGP (Multi-ISP) provides high-quality and high-bandwidth BGP lines.
||BGP (Multi-ISP) Pro lines optimize data transmission to the Chinese mainland and improve connection quality for international services. Compared with BGP (Multi-ISP), when BGP (Multi-ISP) Pro lines provide services to users in the Chinese mainland (excluding data centers), cross-border connections are established by using Chinese mainland ISP services. This reduces network latency.|
|Region||All regions||China (Hong Kong)|
Anti-DDoS Origin Basic can mitigate DDoS attacks at up to 5 Gbit/s. Anti-DDoS Origin Basic meets basic security requirements.
- Anti-DDoS Pro/Premium
Anti-DDoS Pro/Premium can mitigate DDoS attacks at the Tbit/s level. Anti-DDoS Pro/Premium is suitable for users that require advanced security protection and low network latency. When you use Anti-DDoS Pro/Premium, take note of the following limits:
- Only pay-as-you-go EIPs support Anti-DDoS Pro/Premium.
- To use Anti-DDoS Pro/Premium, you must associate an EIP with an EIP bandwidth plan for which Anti-DDoS Pro/Premium is also enabled.
- You can enable Anti-DDoS Pro/Premium only when you purchase an EIP. After you purchase an EIP for which Anti-DDoS Origin Basic is enabled, you cannot upgrade Anti-DDoS Origin Basic to Anti-DDoS Pro/Premium.
- After you enable Anti-DDoS Pro/Premium for an EIP, you cannot disable Anti-DDoS Pro/Premium.
