How to get a static IP for testing? What are the advantages of a static IP?

With the popularity of the Internet, more and more people are starting to use dynamic IPs to surf the Internet. But in some cases, we may need to use a static IP for testing or specific network settings. This article will introduce how to obtain a static IP for testing and the advantages of a static IP.

1. How to obtain a static IP for testing?

1. Contact your ISP (Internet Service Provider)

The easiest way is to contact your ISP and request a static IP address. Most ISPs offer static IP rental services, but they may require additional fees. Before renting a static IP, be sure to understand the details of the service, including usage fees, validity period, whether you need to install a new modem, etc.

2. Use DDNS (Dynamic DNS)

If you don't want to pay extra, you can use DDNS to get a static IP address. DDNS maps a dynamic IP address to a static domain name so that you can use that domain name to access your website or test your network. To use DDNS, you need to choose a DDNS service provider and follow the steps they provide to set it up.

3. Use a VPN (Virtual Private Network)

A VPN allows you to create a secure, encrypted tunnel over the public Internet and access your local network resources through it. With a VPN, you can map your local network's IP address to a static IP address on the external network for testing purposes. You can choose your own VPN service provider, or use an open source solution such as SoftEther.

2. Advantages of static IP

1. Stability

Static IP addresses are highly stable and can ensure the reliability of network connections. Using static IP addresses can avoid connection problems caused by changes in dynamic IP addresses.

2. Security

Static IP addresses are less susceptible to network damage because it is difficult for attackers to find and use dynamic IP addresses to cause damage. In addition, using static IP addresses can also facilitate the setting of firewalls and security policies.

3. Ease of use

For those who need to do network testing or development, using a static IP address can simplify the network configuration process. There is no need to modify the network configuration file or restart the router every time you test the network. As long as you set the static IP address once, you can use it all the time, which is very convenient.

4. Manageability

Using static IP addresses makes network management easier. Administrators can control user access rights and network usage by allocating and managing static IP addresses. In contrast, dynamic IP addresses are more difficult to manage because they change all the time.

In short, it is not difficult to obtain a static IP for testing. At the same time, static IP addresses have the advantages of high stability, security, and ease of use. In the case of network testing or specific network settings, choosing to use a static IP is a very good choice.
