What is an EIP?

An EIP is a static IP address designed specially for dynamic cloud computing. With the help of an EIP, you can quickly remap the EIP to another instance in your account, thus shielding instance failures. An EIP is associated with a tenant account instead of an instance. It is always associated with your account until you decide to unsubscribe from the EIP thoroughly. At present, EIPs can be bound to resources such as ECSs, GPU ECSs, NAT Gateways, DPSs and ELBs.

What are advantages of EIPs?

EIPs have the following advantages:

Flexible binding: EIPs can be flexibly bound to cloud resources. You can bind EIPs to ECSs as required to access the Internet at any time. Through one-to-one mapping, you can also select an ELB to bind after binding an ECS.

Network adaptation: Different business scenarios require different bandwidth specifications of EIP. You can flexibly adjust network bandwidth as required to achieve bandwidth adaptation.

Independent management: In the eSurfing Cloud Console, the EIP lifecycle can be independently managed.

Diversified billing: EIPs support multiple billing modes. You can select billing by annual or monthly package as required or select billing by hours of use or actual traffic.

How many EIPs can one account apply for?

The default quota of EIPs is 20. If you need to increase the quota, you can submit a ticket. Because EIP resources are limited, please ensure that each EIP is used for legal purposes. EIPs seized maliciously may be forcibly taken back by eSurfing Cloud.

Can an EIP be used to resolve website domain name?

Yes. When an EIP is used to resolve the domain name of a website, you also need to perform related operation such as filing. The content of your website should comply with national laws and regulations.
