弹性公网 IP
弹性公网 IP(Elastic IP,EIP)是可以独立购买和持有,且在某个地域下固定不变的公网 IP 地址,可以与 CVM、NAT 网关、弹性网卡和高可用虚拟 IP 等云资源绑定,提供访问公网和被公网访问能力;还可与云资源的生命周期解耦合,单独进行操作;同时提供多种计费模式,您可以根据业务特点灵活选择,以降低公网成本。
高性能、安全性、稳定性及高可用性
弹性灵活

弹性公网 IP 是独立的公网 IP 资源,属于您的腾讯云账户。您可随时与 CVM、NAT 网关、弹性网卡和高可用虚拟 IP 等绑定、解绑,灵活使用。此外,还可以动态调整带宽,实时生效。

更低成本

弹性公网 IP 提供多种计费模式,包括按流量、按小时带宽、按包月带宽计费等。您还可以将按流量和按小时带宽计费模式的 EIP 加入共享带宽包,提高带宽资源的利用率,大幅降低您的公网使用成本。

满足您需求的多元化解决方案
提供公网访问能力
容灾
提供公网访问能力
弹性公网 IP 可以与 NAT 网关绑定,通过 NAT 网关的 SNAT 和 DNAT 功能,为多个无公网 IP 的 CVM 提供访问公网能力和被公网访问能力。
容灾
在多活容灾场景中,主云服务器和备用云服务器的应用和资源实时同步。主云服务器与弹性公网 IP 绑定,当主云服务器故障时,可以将弹性公网 IP 与主云服务器解绑并重新绑定到备用云服务器中,将业务使用的公网 IP 从故障的主云服务器平滑迁移到备用云服务器,无需修改 DNS 等映射关系,保证服务的连续性。
FAQS

Frequently

asked questions

Can I Change a Public IP Address?

Yes, you can change the public IP address for the CVM. For the specific operations, see Changing the Public IP Address for an Instance.

What Can EIP Do?

EIP is suitable for the following scenarios:

  • Disaster recovery. In multi-active disaster recovery scenarios, applications and resources on the primary and standby servers are synchronized in real time. When the primary server is bound to an EIP, if the primary server fails, you can unbind the EIP from the primary server and rebind it to the standby server. This enables smooth migration of the EIP used by services from the failed server to the standby server without modifying DNS or other mapping configurations, ensuring business continuity.
  • Specific public IP address retaining. If you want to retain a specific public IP address in your account, convert it into an EIP. After binding/unbinding the EIP from a device, you can use it for public network access. As long as you do not perform a "release" operation, this EIP permanently retains in your account.
  • Other special scenarios. If you need to replace an IP address in other special scenarios, convert a regular public IP address into an EIP and then binding/unbinding the EIP. However, EIP resources are valuable with regional quota limits for a single account. It is recommended that you plan and use them rationally.
How to Protect Against Network Vulnerabilities on the Business Side of Cloud Resources Bound to an EIP?

Using Cloud Firewall (CFW) helps you quickly identify assets and vulnerabilities exposed to the Internet and enables protection with one click. For details, see Cloud Firewall.

How Are IP Address Resource Fees Charged for EIP?

1. The fee displayed in the console applies to EIPs that have been idle for more than 1 hour. Currently, IP address resources can be charged accurately to seconds. For EIPs that have been bound/unbound for multiple times, IP address resources are charged based on the total duration for which they are unbound.

2. For EIPs that have been idle for less than 1 hour, IP address resources are charged based on the proportion of idle time.

For details about how IP address resource fees are charged for EIP, see IP Address Resource Fees.

How to Stop EIP Charges?

If you no longer require an EIP in the Unbound and Charging status, release the EIP. No IP address resource fees are generated for a released EIP. For detailed operations, see Releasing an EIP.

If you want to retain an EIP in the Unbound and Charging status but do not want the IP address resource fees to be generated, bind the EIP to cloud resources such as CVM, NAT Gateway, ENI, and HAVIP resources. No IP address resource fees are generated for an EIP that is bound to cloud resources.
