Static and dynamic IP address: Everything you need to know

If you are an Internet user, you must encounter at least the term \”IP address\”. In fact, each electronic device on the Internet has its own IP address, which means that there are billions of IP addresses now.

Obviously, they are an indispensable part of the computer network, playing an important role in data exchange. In fact, you will not be able to surf the Internet without IP.

There are four main types of IP. But today, we will discuss the two in detail, static and dynamic IP addresses. In addition, this article will explain how to check your IP address.

What is an IP address?

The internet protocol (IP) address is the unique identifier of the Internet or hardware devices on the network.

In other words, the identity of the IP address provides devices on the Internet is similar to family or company address. They will help the devices on the network can distinguish, share and communicate with each other. Simply put, different devices have different IP addresses.

For example, if you want to send parcels to friends in another country, you need to know him/her/her Expert address. In other words, you must write down the specific address by finding in the phone book. Not just write down your friend’s name and expect the package to reach the right position.

The process of sending and receiving data through the network is similar to the above example. However, computer uses the domain name system (DNS) server to find the host name to find its IP address instead of a telephone book.

For example, you enter a web page through the browser, such as passwordprotectwp.com. The request loaded this page will be sent to the DNS server. Then your computer will find the host name (PasswordProtectwp.com) to find its corresponding IP address. Without an additional IP address, your computer will not know what it is looking for.

4 IP addresses

The IP address has 4 main types: private, private, Public, static and dynamic IP address.

Private IP address

: They are also called internal IPs. You can manuallyOr automatically set them. They appear on internal networks, such as schools, companies or organizations. Private IP can only be connected to the local network through routers. This means that your computer cannot communicate directly with the router you connect to them.

Public IP address

: Unlike the private IP address, the public IP address is community IP. Your computer will be authorized to access the global network and communicate between routers. Simply put, you can access any information on the global network.

Static IP address

: These IPs are essentially fixed and will not change over time. You must manually configure the static IP address for the device on the network. Static IP is a fixed address retained for a user or a group. It is usually assigned to servers with specific uses, such as mail server, web server, etc.

dynamic IP address : These IP will automatically allocate to every on the network every other on the network Connect or nodes, such as mobile phones, desktops or tablets. Dynamic host configuration protocol (DHCP) server will customize the IP address of the custom device on the network. In other words, dynamic IP will be changed regularly.

Public and private IP indicator devices (inside or outside the local network), static and dynamic IP indicate their stability. In this article, we will focus on the difference between static IP addresses and dynamic IP addresses.

The reason for using the static IP address

Use static IP may bring you many benefits:

Convenient

: Static IP address Make connections faster, because users do not need to re -release new IPs. Simply put, static IP is similar to email or home address. It will not change, convenient communication and use.

reliability
• : The working environment of multiple computers, business fax machines or systems should be considered. They will reduce the risk of data loss to the greatest extent and help computers work more stablely.

Stability

• : The static IP address will not change, which will usually lead to a more stable connection.

accuracy

• : With static IP, the computer can accurately know your real location. For example, you use static IP to log in to the weather forecast website. Then you will get the weather report you need, not another city.

除了这些优点之外，静态IP 还有一些明显的缺点：

[123 ] Time -consuming process : The biggest disadvantage of static IP is that you must manually configure the device. You not only need to use the IP address setting device, but also the correct configuration router to communicate with the address. So it takes a lot of time and energy.

Weak security

: Because static IP will never change, hackers are more likely to find vulnerabilities.
• High cost

: The use of static IP addresses is not an economical method, because their fees are usually much higher than dynamic IP.

• Dynamic IP address
• Dynamic IP address benefit you in many aspects:

Flexibility

: Dynamic IP address ratio Static IP addresses are more flexible. For example, a specific IP address will be assigned to a laptop on the network. When the laptop is disconnected from the network, the address will be used by another device on the network.

Using this type of IP address, the number of devices connected to the network is not limited. The offline device will be disconnected and the address memory is released to other devices.

Simple : You don’t have to manually manually make new new connecting to the network new network Device allocate IP address. All you need to do is to enable DHCP on the router. It will automatically configure the IP address for your device. Security

Sex: Contrary to static IP, the continuous changes in dynamic IP make it difficult for hackers to find your exact address. Therefore, it is almost impossible to track your device and your physical location.

• Low price : As mentioned above, the cost of setting a dynamic IP address is usually not as expensive as static IP.

This type of IP will produce certain benefits, but there are some shortcomings:

Not compatible

• : Due to the dynamic IP address Continuous changes, you may encounter some troubles, such as IP conflicts on your computer. For example, if you want to host an email server, you should not use a dynamic IP address. This is because DNS clothingThe workers usually do not handle the dynamic IP address well.

Slow connection

: Due to the continuous change, the dynamic IP address will slow down your internet connection speed.
