To keep the public IP address unchanged, you typically need to reserve or allocate a static IP address. Unlike dynamic IP addresses that can change each time a device connects to the internet, a static IP remains constant.
Explanation:
When you reserve a static IP address, it ensures that your device always has the same IP address, which is useful for services that require consistent connectivity, such as VPNs, remote desktop connections, or hosting a server.
Example:
Imagine you are running a web server and you want users to be able to access it consistently. By assigning a static IP address to your server, users can always connect to the same address, ensuring that your website remains accessible without interruptions due to IP changes.
Cloud Service Recommendation:
If you are using cloud services, platforms like Tencent Cloud offer the ability to reserve static IP addresses. On Tencent Cloud, you can allocate an Elastic IP (EIP) and bind it to your cloud server, ensuring that the public IP address remains unchanged. This is particularly useful for applications requiring stable and reliable external access.
