Why do LAN IPs usually start with 192.168 instead of 1.2 or 193.169?

## People who configure routers often The router's default IP address will be used as the gateway. Changing it to another IP address is both confusing and troublesome.

Why do LAN IP addresses like 10.X.X.X, 176.16.X.X and 192.168.X.X appear?
That’s because there was already a shortage of IPv4 addresses as early as the mid-1990s. So someone started thinking: IP addresses cannot be repeated. Repeating them means that the data will be sent incorrectly. However, you can determine a private domain IP address for everyone to use within the LAN for free. These private domain IP addresses can be reused in different LANs, as long as you ensure that there are no duplicate IP addresses in the same LAN. NAT technology (Network Address Translation) was born in this scenario. In addition, search the public account's top algorithm backend to reply "Algorithm Experience" to get a surprise gift package.


## It is not so much that the current LAN IP usually starts with 192.168 instead of 1.2 or 193.169, because of network technology the result of evolution. The editor is more willing to believe that this is due to people's habits. This is just like how we walk or drive on the right now. If one day it is required to drive on the left, then every city will definitely be in chaos. Traffic regulations are also based on the original public trust before they can become effective regulations. The same is true for IP address planning.
The above is the detailed content of Why do LAN IPs usually start with 192.168 instead of 1.2 or 193.169?. For more information, please follow other related articles on the PHP Chinese website!

Local area network lan refers to a network within 10 kilometers. A local area network refers to a regional network formed in a local area. It is characterized by a limited distribution area, generally limited to less than 10km (kilometers), and is usually connected by wired methods. A local area network connects various computers, external devices and databases in a certain area to form a computer communication network, and connects to local area networks or databases in other places through dedicated data lines to form a larger information processing system.

Reasons for using an intranet: 1. Resource sharing, which can provide convenient sharing of software and hardware resources, especially in the direction of hardware resources. Office automation equipment such as printers and scanners are fully utilized. 2. Facilitate teamwork. Most modern LANs provide a platform that allows multiple users to work on the same file and always use the latest version. 3. It is easy to find information, and the intranet can be used as a place to place all trusted information. 4. Reduce management costs. With the help of the intranet, online forms can be easily provided, streamlining the work process from the beginning, and greatly improving work efficiency.
