Why can't purchased EIPs be found or displayed in the Console?

It may take some time to create an EIP. You can view the availability zone of subscription and the availability zone of the Console, find subscription records from the order page and then view the availability zone of subscription.

Why can't I access an EIP?

If you cannot access an EIP, possibly the EIP is not bound to a cloud resource or the EIP is in arrears. If the EIP is bound to an ECS and still cannot be accessed, check whether the ECS is configured with a security policy.

What is the policy for assignment of newly applied EIPs?

By default, EIPs are assigned randomly. We cannot guarantee that the specified EIPs can be assigned.

Does EIPs support specifying addresses or recovering addresses that have been used?

At present, the Internet addresses of EIPs are automatically assigned and cannot be specified. Once EIPs are released, when EIPs are created again, we cannot guarantee that the same EIPs can be recovered.

Which cloud resources can EIPs be bound to?

At present, EIPs can be bound to resources such as ECSs, GPU ECSs, NAT Gateways, DPSs and ELBs.

Can one EIP be bound to multiple cloud resources at the same time?

No. One EIP can be bound to only one cloud resource.

Do EIPs support binding across regions?

Not supported. To guarantee user experience, please ensure that EIPs and the cloud resources to which the EIPs will be bound are set in the same region.

Do EIPs support binding across availability zones?

Supported. EIPs can be used normally so long as they belong to the same region as cloud resources and the both do not need to be in the same availability zone.

An EIP has been bound to an ECS instance. Can Internet services still be provided through the DNAT function of the NAT gateway?

Yes. When an ECS binds an EIP and is configured with DNAT rules, it can be accessed by either the EIP or DNAT.

Note: The two access modes use different ports. In addition, pay attention to the network access configuration.

Why can't an EIP be bound to an ECS instance?

The possible reasons are follows:

The EIP and the ECS are not in the same region;
The ECS is powered off. An EIP can be bound to only an ECS in a running or stop status.
The ECS is bound to another EIP.

An ECS instance can be bound to only one EIP. How to associate one ECS instance with multiple EIPs?

You can create multiple NICs, bind an EIP to each NIC, and then bind these NICs to one ECS instance.

Note: The number of auxiliary elastic NICs supported by each instance specification in billing is different.
