In the Internet world, IP address is a "passport" that uniquely identifies a device's location in the network. According to the different ways of use, IP address can be divided into 1m exclusive IP and 2m shared IP two types. So, what is the difference between these two types of IP addresses? What are their respective characteristics? Here, let me give you a detailed introduction.

1、1m Dedicated IP: Each device occupies one IP exclusively

1m Exclusive IP, as the name suggests, is an IP address that is exclusive to each device. The biggest advantage of this usage is that it can provide each device with an independent identity, enabling isolation and interconnection between devices. For example, if you are a network administrator in a company, you might assign an exclusive IP to each employee's computer, which improves network security and allows you to accurately track employee network behavior.

In addition to improved security, 1m dedicated IPs offer better stability and speed. Since each device has an independent IP address, there will be no network interruption due to problems with other devices. At the same time, for some scenarios that require high network speed, such as online games, live video streaming, etc., 1m Dedicated IP can also bring lower latency and smoother experience.

Of course, 1m Dedicated IP also has some shortcomings. First of all, the cost is relatively high, because each device needs to have a separate IP address, so the number of IPs to be purchased will increase accordingly, which may be a considerable expense for some small businesses or individual users. Secondly, 1m dedicated IP may be slightly insufficient in terms of resource utilization, although each device has an independent IP address, but there may be some IP address is not fully utilized.

2、2m Shared IP: Multiple devices share one IP

2m Shared IP means that multiple devices share an IP address. The biggest advantage of this usage is that it can save IP address resources and alleviate the problem of IP address shortage to some extent. Under 2m shared IP, different devices are distinguished from each other by port numbers, thus realizing mutual access and communication between devices.

2m shared IPs are more common in businesses and individual users. For example, in an office environment, multiple computers may share an IP address, which enables multiple computers to share the same network outlet, thus reducing costs.

However, compared with 1m exclusive IP, 2m shared IP also has some problems. Firstly, the security is relatively low, because multiple devices share one IP address, once one of them has problems, it may affect the normal use of other devices. Secondly, the speed and stability are also relatively poor, because multiple devices share an IP address, so the network bandwidth, traffic and other resources will be shared by multiple devices, which can easily lead to congestion and delay.

To summarize, 1m exclusive IP and 2m shared IP have their own advantages and disadvantages. For some scenarios with higher requirements on network security, speed and stability, it is more suitable to choose 1m exclusive IP; while for some scenarios with higher requirements on cost saving and resource utilization, it is more suitable to choose 2m shared IP.

Whether it is 1m exclusive IP or 2m shared IP, they are both designed to serve users better. If you are a network administrator, you need to choose a suitable IP usage for yourself according to the actual needs. For ordinary users, as long as they can surf the Internet smoothly and have a good experience, they do not need to be too entangled in whether it is a 1m exclusive IP or a 2m shared IP. In the world of the Internet, the IP address is our "pass" to swim in the network, whether it is 1m exclusive IP or 2m shared IP, can bring us a better online experience.
