Belajar Dasar Jaringan Komputer dari nol - Part 6/8 | IP Public dan Private

Summary

In this video, the concepts of Public and Private IP addresses are explained. A Public IP allows devices to connect to the internet and is regulated by authorities like IANA and regional registries. It is essential for global communication. In contrast, Private IPs are used within local networks for communication among devices, and they are not routable on the internet. The video highlights the importance of both types of IP addresses, with Public IPs enabling internet access and Private IPs facilitating local network communication. The process of obtaining and using both is also discussed, including examples of Private IP ranges.

Takeaways

• 😀 A public IP is used to connect us to the internet, enabling communication on the web.
• 😀 Public IPs are regulated and assigned by organizations like AFRINIC, APNIC, and LACNIC.
• 😀 In Indonesia, the IDNIC (Indonesia Network Information Center) is responsible for assigning public IPs.
• 😀 A public IP is required for internet access, while a private IP is used for local or internal networks.
• 😀 Private IPs are used for local communication within organizations or offices.
• 😀 Private IP ranges include 10.0.0.0 – 10.255.255.255, 172.16.0.0 – 172.31.255.255, and 192.168.0.0 – 192.168.255.255.
• 😀 Private IPs cannot be used on the internet and are typically kept within local networks.
• 😀 Public IPs and private IPs work together for internet communication and local network operations.
• 😀 Public IPs are assigned by regional authorities to ensure worldwide internet connectivity.
• 😀 The script emphasizes the importance of understanding the differences between public and private IPs for proper networking.

Q & A

What is a public IP?

A public IP is a unique address assigned to a device for communication on the internet. It connects your device to the worldwide network and is managed by authorities like regional internet registries.

How is a public IP assigned?

Public IPs are assigned by regional internet registries (RIRs) like AFRINIC, APNIC, and LACNIC. In Indonesia, the IP allocation is managed by IDNIC (Indonesia Network Information Center).

What is the purpose of a public IP?

The main purpose of a public IP is to enable devices to communicate over the internet, acting as a unique identifier for those devices.

What is a private IP?

A private IP is used for communication within a local network, such as within an office or home network. These addresses cannot be accessed directly from the internet.

What are some examples of private IP address ranges?

Private IP address ranges include: 10.0.0.0 to 10.255.255.255, 172.16.0.0 to 172.31.255.255, and 192.168.0.0 to 192.168.255.255.

Can private IPs be used to access the internet directly?

No, private IPs are for local network communication and cannot be accessed directly from the internet. A public IP is required to connect to the internet.

How are private IPs typically used?

Private IPs are used in internal networks, such as within offices or homes, to allow devices to communicate with each other without exposing them to the public internet.

How does a device with a private IP access the internet?

A device with a private IP typically uses a router or gateway with a public IP to access the internet. The router handles the translation between private and public IPs.

What is the main difference between a public IP and a private IP?

The key difference is that a public IP is used for communication on the internet and is globally unique, while a private IP is used within a local network and is not directly accessible from the internet.

Why is it important to understand the difference between public and private IPs?

Understanding the difference helps in network design and management, ensuring that devices are assigned the correct IP type based on their communication needs—whether it's internal networking or internet access.
