IP address and something you need to know about it

Although the IP address is quite familiar, there are a lot of people who still don’t understand the concept and how the Internet Protocol works, providing utility for users. Therefore, we will provide you important knowledge about IP addresses as well as methods of installing IPs on your computer. Hopefully, through this article, you will better understand the Internet Protocol system.

What is IP?

Each computer (called a host) on the Internet has at least one unique IP address to determine the difference among all other computers on the Internet. Normally, by type of internet, we will see two types of IPs in internet activities. It is an IP LAN for example 192.168.xxx.xxx and Modem’s public IP gives the internet for us. Each modem will have a separate public IP address. 

This IP does not match any other IP. When using 3G or 4G, you also have a separate public IP. However, 2 different intranets exist 2 identical IPs are extremely understandable. But, public IP only exists. Public IP has 2 main types: IP for individuals and IP broadcast (IP broadcast is IP used in the data center).

Structure of IP address

Currently, all types of IP addresses are divided into two types: IPv4 addresses and IPv6 addresses.

  • IPv4 address: IPv4 uses 32 bits to encrypt data in the form: EFG.HIJK.LMN.OPQ (for example, the Internet Protocol (IP) may be: 103.1.208.205). Numbers will be created by the network specialist or the related Modem device. However, due to the rapid development of the internet, IPv4 addresses are gradually exhausted, the time of existence is only in months. To overcome this problem, service providers have built IP with IPv6 protocol.
  • IPv6 Address: IPv6 uses 128 bit to encrypt data. The number of IPs that IPv6 can provide is very large, it can reach numbers (4 * 10 ^ 4) ^ 4. With such a huge number, IPv6 can ensure the supply of IP in a very long time around the world. But the deployment of IPv6 is also facing difficulties due to configuration errors for previous IPv4 devices.

Dynamic IP address and static IP address

In addition, people also divided IP addresses into two types: static IP and dynamic IP. However, why do I have to set a static IP and dynamic IP for my computer? Let’s find out with us.

Dynamic IP address

Dynamic IPs are automatic IP addresses assigned to each connection, or nodes on the network, such as mobile devices, computers, tablets…

The automatic IP assignment is done by the DHCP server. The DHCP server assigns an IP address called a dynamic IP because this address will change with each different network connection in the future. When you check the IP on the computer, if you see that the IP is changed automatically after a period of time, it is a dynamic IP, and if you see that the IP is not changed automatically, it is static IP.

Changing IPs makes it easier for you to access websites that are blocked

Changing IPs is also the way you want to hide the network address information where you work and study, avoiding the eyes from outside.

In contrast to dynamic IPs are static IPs (IP addresses are manually configured). Public IPs are assigned on routers used in households and businesses because their Internet service providers use dynamic IPs. For large companies, they don’t use dynamic IPs to connect to the Internet; instead, they only use the assigned static IPs.

The advantage of an automatic IP address assignment is set up and managed easily. With this type of automatic IPs assignment, there is little limit on the number of devices that can connect to the network because devices that do not need to connect to the network will disconnect and release the memory address for another device.

Static IP address

Static IP is interpreted as fixed or unchanged. Static IPs are installed permanently on a user’s computer or on servers.

At the normal user level, static IP on the LAN can be set up in the Network and Sharing Center of the Microsoft Window operating system. IP Hosting/VPS/Server in the data center is also static IP.

Static IP (at the internet level of ordinary users), every time you restart Modem, the IP does NOT change.

Why do we have to set static IPs and dynamic IP for computers?

IP addresses for personal computers and other mobile devices are automatically installed by the router using the DHCP protocol. It can be said that this is a quite convenient method to connect network devices together because users do not have to configure IPs for any device. However, the disadvantage of assigning an IP is that this address may change over time.

You cannot use static IP addresses in any case

However, in some cases, users can only use static IP addresses such as:

  • When there are some applications that can only connect to a certain IP address, when connecting to a new IP, it does not work.
  • When you want to transfer ports through the router to network devices. There are routers that can use both static and dynamic IPs, but some only accept static IPs…

Therefore, users need to know how to set static IPs and dynamic IPs for computers to be able to manipulate other devices, applications, and websites easily.

Instructions on how to set a static IP address and dynamic IP for your computer

There are many different ways to set static IP s and dynamic IPs for computers. However, all ways are aimed at the ultimate goal of connecting with other devices easily. The content of the article below, we will send you how to set static IPs and dynamic IP for your computer.
