云服务器的ip地址是固定的吗

云服务器的ip地址是固定的吗？

云服务器的使用越来越广泛了，它可以为企业提供高效、弹性的 IT 服务，但是很多人对于云服务器的 IP 地址是否固定还存在疑问。下面就让我们一起来了解一下吧。

云服务器的 IP 地址是固定的还是动态的呢？答案是取决于云服务器的类型。在传统的物理服务器中，服务器的 IP 是静态的，每个服务器都拥有唯一的 IP 地址。但云服务器则不同。在云服务器中，IP 地址分为内网 IP 和公网 IP。

1. 内网 IP

内网 IP 通常是由云平台自动分配的，由云平台控制的虚拟网络内客户端之间的交互使用。在同一云平台内，整个内网 IP 是固定的。也就是说，在同一个云平台中，内网 IP 是固定的，不会因为实例重启或者更换而改变。

2. 公网 IP

公网 IP 属于互联网 IP，通常被用来与外部进行交流。在云平台中建立一个云服务器时，公网 IP 是根据用户需求或者云平台规定的分配方式进行分配的，但在实例释放后，公网 IP 会被回收到 ip 地址池中，而新分配出去的实例的公网 IP 可以是与原来实例的公网 IP 不同。所以，可以说云服务器的公网 IP 是动态的。

总而言之，云服务器的 IP 是否固定取决于不同的类型。不过，很多云平台提供了弹性公网 IP，通过绑定和解绑，可以为不同的云服务器提供更灵活的 IP 管理方式。在云服务器的使用中，用户可以根据自己的需求，采取不同的措施进行运维。

Is the IP address of the cloud server fixed?

Cloud servers are widely used today to provide efficient and elastic IT services to businesses. However, there are still questions about whether the IP addresses of cloud servers are fixed or not. Let us take a closer look.

Are the IP addresses of cloud servers fixed or dynamic? The answer depends on the type of cloud server. In traditional physical servers, the server’s IP is static, with each server having a unique IP address. In contrast, cloud servers are different. In cloud servers, IP addresses are divided into internal and external IPs.

1. Internal IPs

Internal IPs are usually automatically allocated by the cloud platform and used for interactions between clients within the virtual network controlled by the cloud platform. In the same cloud platform, the entire internal IP is fixed. In other words, in the same cloud platform, the internal IP is fixed and will not change due to instance restart or replacement.

2. Public IPs

Public IPs belong to Internet IPs and are usually used to communicate with external parties. When a cloud server is created on a cloud platform, the public IP is assigned based on user requirements or the allocation methods set by the cloud platform. However, after an instance is released, the public IP is reclaimed and returned to the IP address pool, and the public IP assigned to a new instance may be different from that of the original instance. Therefore, the public IP of the cloud server is dynamic.

In summary, whether the IP of the cloud server is fixed depends on different types. However, many cloud platforms provide elastic public IPs, which offer more flexible IP management by binding and unbinding. When using cloud servers, users can adopt different measures for operation and maintenance according to their own needs.
