Private Network
A private network is a network that is created for use by a specific individual or group, usually in a limited place such as a home, office, or institution. This network allows devices to securely connect and share resources such as files, printers, and internet access.
The main characteristics of a private network include:
- Security: Private networks typically come with stricter security measures, such as the use of passwords and encryption, to protect data from unwanted access.
- Access Control: Users have full control over who can connect to the network and what resources they can access.
- Performance: Since these networks are usually limited to a limited number of devices, they can perform better compared to public networks that have a lot of users.
- Flexibility: Users can easily add or remove devices from the network as needed.

Private IP Address and Its Function
A private IP address is an address that is used in a private network and cannot be accessed directly from the Internet. These addresses are designed for local networks and help save on the use of public IP addresses. Some of the most commonly used private IP address ranges are:
- 10.0.0.0 to 10.255.255.255
- 172.16.0.0 to 172.31.255.255
- 192.168.0.0 to 192.168.255.255
There are several advantages to using a private IP address:
- Security: Private IP addresses make devices on the network inaccessible from the outside, reducing the risk of attacks from the Internet.
- Public IP Address Savings: With a private IP address, multiple devices in a local network can share a single public IP address when connected to the Internet via NAT (Network Address Translation).
- Easier Network Management: Private IP addresses make it easy to manage devices within a local network without the need for complicated configurations.
Conclusion
This article discusses the basics of Internet technology and ways to connect. TCP/IP is a protocol that regulates communication between devices by dividing data into small packets. Subnet mask serves to divide the network into sub-networks, while DNS translates domain names into IP addresses that can be understood by the device.
When choosing an Internet service, it is important to pay attention to the price, speed, devices provided by the ISP, and customer service support. Existing connection methods include dial-up, cable, DSL, and wireless (Wi-Fi), each with its advantages and disadvantages.
