An IP address stands for Internet Protocol and is a numerical address used to uniquely identify devices connected to the internet. IP addresses typically use two formats: IPv4 and IPv6. An IP address can be used to identify a device's location and to communicate with other devices. Each device must have an IP address to connect to the internet.

When discussing IP addresses, static and dynamic IP addresses are often mentioned. A static IP address refers to a fixed IP address assigned to a device, meaning that each time the device connects to the internet, it will use the same IP address. This type of IP address is commonly used for servers, gaming consoles, or other network devices that require frequent access.

A dynamic IP address refers to a new IP address being assigned to a device each time it connects to the internet. This type of IP address is commonly used for home networks where users do not need to remotely access home devices frequently.

Why use a static IP address?

A static IP address allows devices to maintain the same IP address, making them easier to locate and useful for applications that require remote access. For example, a static IP address can ensure that a device can always be found when setting up servers, VPNs, or remote desktop connections.

How to obtain a static IP address?

Generally, a static IP address needs to be requested from your internet service provider (ISP). You can contact your ISP and request them to assign a static IP address to you. Some ISPs may charge additional fees for this.

Advantages of a static IP address

① High stability

Static IP addresses do not randomly change, making your network connection more stable.

② Easy accessibility

A static IP address makes it easier for others to find your device, such as your server, gaming console, etc.

③ High security

A static IP address can be used to set stronger security measures to prevent unauthorized access.

Disadvantages of a static IP address:

① High cost

As the number of IP addresses is limited, dynamic IP addresses can effectively mitigate this problem, while static IP addresses usually require additional fees, whereas dynamic IP addresses are usually free.

② Complicated configuration

Installing and configuring a static IP address may be more complex than a dynamic IP address.

An IP address is a numerical identifier used to identify a device connected to the internet. If an IP address is leaked, a user's significant information, including their geographical location, ISP provider, operating system, and browser type, among others, can be used by advertisers, hackers, or other malicious actors to track the user's actions and personal identity. Therefore, protecting IP addresses from being leaked is an essential part of internet security.

How can we protect our IP address?

Using MetroVPN is a nice choice. When you use MetroVPN, it assigns you an alternative IP address. This means that your real IP address and location will be hidden, blocking many malicious activities from tracking your actions. By using servers in different regions, you can simulate geographic locations outside your area and access content blocked in certain countries/regions.

Moreover, MetroVPN uses encryption technology to protect your data, making it impossible for hackers and third parties to steal your sensitive information. It ensures your data and communication are protected on the internet, preventing third-party monitoring of your activities.

However, please note that MetroVPN can only protect your network traffic during VPN connection time. Once you disconnect and return to your original IP address, your data and traffic will be exposed on the internet. Therefore, it is recommended that you always use MetroVPN in online activities related to sensitive information and consider public Wi-Fi and other insecure network environments carefully.
