Are the IPs built out of cloud servers natively exclusive IPs?

The concept of cloud servers is becoming more and more familiar to people, which can realize the deployment and operation of various applications on the cloud platform conveniently. However, many people have doubts about whether the IP of the cloud server is natively exclusive. In this article, we will analyze this issue from several aspects and take you to explore the mystery of cloud server IP.

First, how do you get the IP of the cloud server?

Before we start delving into this, let's talk about how the IP of a cloud server is obtained. When we buy a cloud server, the cloud service provider assigns us an IP address that can be used to access our cloud server. However, this IP address is not unique to us and may be used by other users.

Second, is the IP of the cloud server exclusive?

The answer to the question "Is the IP of the cloud server exclusive" is actually differentiated. Let's take a look at two common types of cloud server IPs.

1. Shared IP

On a cloud platform, there may be many users using the cloud server at the same time, which means they may share IP addresses. At this point, the IP used by our cloud server is not natively exclusive, but is rotated by multiple users.

2. Exclusive IP

In some high-end cloud server service providers, the feature of exclusive IP is also provided. In this case, the IP used by our cloud server is exclusive and cannot be used by other users. This time, our application can have better stability and privacy.

C. How to get an exclusive IP?

So what should we do if we wish to get an exclusive IP address? I will give you a common method below.

1. Elastic IP

Elastic IP is an IP address service provided by cloud server providers that enables dynamic binding and unbinding of IP addresses. By using Elastic IP, we can easily bind an IP address from one instance to another, realizing IP address exclusivity.

Code Example:

# Apply for a Flexible IP
'''
import boto3

ec2 = boto3.client('ec2')
response = ec2.allocate_address(Domain='vpc')

print('Allocated elastic IP:', response['PublicIp'])
'''

# Bind elastic IP to instance
'''
import boto3

ec2 = boto3.client('ec2')
response = ec2.associate_address(InstanceId='your-instance-id', PublicIp='your-elastic-ip')

print('Associated elastic IP with instance:', response['Return'])
'''

By using Elastic IP, we can easily realize the exclusivity of cloud server IP to improve the stability and access quality of applications.

IV. Summary

To summarize, although the IP addresses of cloud servers are not always natively exclusive, by using some technical means, such as elastic IP, we can realize the exclusivity of cloud server IPs. In this way, our applications can have better stability and privacy. I hope the analysis in this article can help you, more questions about cloud servers, welcome to exchange discussions.
