Elastic IP Address:Overview

Last Updated:Sep 19, 2023

An elastic IP address (EIP) is a public IP address that you can purchase and use as an independent resource.

Line type

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.

  • Provides high-quality BGP lines across the globe.

  • Uses BGP lines from different ISPs at the same time and automatically selects the optimal BGP line to ensure network stability.

    Supported ISPs are China Telecom, China Unicom, China Mobile, China Mobile Tietong, China Netcom, CERNET, NRTA, Dr.Peng Group, and Founder Broadband.

  • You can use BGP (Multi-ISP) with EIP bandwidth plans to obtain bandwidth of 100 Gbit/s and higher.

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.

Supported regions

All regions

China (Hong Kong), Japan (Tokyo), Singapore, Malaysia (Kuala Lumpur), Philippines (Manila), Indonesia (Jakarta), and Thailand (Bangkok)

Note

BGP (Multi-ISP) Pro lines support only the pay-as-you-go billing method in the following regions: Japan (Tokyo), Singapore, Malaysia (Kuala Lumpur), Philippines (Manila), Indonesia (Jakarta), and Thailand (Bangkok).

Anti-DDoS editions

By default, EIPs support Anti-DDoS Origin Basic to protect your services. If you have higher security requirements, you can choose Anti-DDoS Pro/Premium.

  • Default

    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 ideal 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

    • 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.

    • The following regions support EIPs integrated with Anti-DDoS Pro/Premium.

      Area

    Important

    If you use EIPs integrated with Anti-DDoS Pro/Premium, take note of the following information:

    • If this is your first time using EIPs integrated with Anti-DDoS Pro/Premium, you must first click Anti-DDoS Origin Basic (pay-as-you-go) to activate Anti-DDoS Origin Basic (pay-as-you-go).

    • When you use EIPs integrated with Anti-DDoS Pro/Premium, you are charged an Anti-DDoS fee. For more information, see Pay-as-you-go.
