Which of the Following Are Non-routable IP Addresses? (Select All That Apply)

In computer networking, IP addresses play a crucial role in establishing communication between devices. However, not all IP addresses are created equal. Some IP addresses are classified as non-routable, meaning they cannot be used for direct communication over the internet. Let’s explore which IP addresses fall into this category.

Non-routable IP addresses are used for internal network purposes, such as local area networks (LANs) or private networks. These addresses are reserved and cannot be routed over the internet. The following IP address ranges are considered non-routable:

1. 10.0.0.0 to 10.255.255.255 (10.0.0.0/8)
2. 172.16.0.0 to 172.31.255.255 (172.16.0.0/12)
3. 192.168.0.0 to 192.168.255.255 (192.168.0.0/16)

These ranges are defined in the Internet Engineering Task Force (IETF) Request for Comments (RFC) 1918. Non-routable IP addresses are often used within organizations to manage internal network traffic and maintain security.

FAQs:

1. Why are non-routable IP addresses used?
Non-routable IP addresses are used to create private networks within an organization. They allow for efficient internal communication without exposing devices to the public internet.

2. Can non-routable IP addresses be used for internet communication?
No, non-routable IP addresses cannot be directly used for internet communication. They require network address translation (NAT) to be converted into routable IP addresses.

3. Are non-routable IP addresses secure?
Non-routable IP addresses provide an additional layer of security by making internal network devices inaccessible from the internet. However, additional security measures are still necessary to protect against internal threats.

4. Can non-routable IP addresses be accessed from the internet?
Non-routable IP addresses are not accessible from the internet, as they are not routable. To access devices with non-routable IP addresses, virtual private networks (VPNs) or other remote access methods are required.

5. Can non-routable IP addresses be used for local network communication?
Yes, non-routable IP addresses are primarily used for local network communication within an organization. They allow devices to communicate with each other without the need for public internet access.

6. Are there any disadvantages to using non-routable IP addresses?
One potential disadvantage is the need for network address translation (NAT) to convert non-routable IP addresses into routable ones for internet communication. Additionally, using non-routable IP addresses may require more complex network configurations.

7. Can non-routable IP addresses be used for website hosting?
No, non-routable IP addresses cannot be used for hosting websites directly. Websites require routable IP addresses to be accessed over the internet.

8. How can non-routable IP addresses be converted into routable ones?
Non-routable IP addresses can be converted into routable ones using network address translation (NAT). NAT allows multiple devices with non-routable IP addresses to share a single routable IP address for internet communication.

In conclusion, non-routable IP addresses are essential for creating private networks within organizations. They cannot be directly accessed from the internet and require network address translation (NAT) for internet communication. Understanding the concept of non-routable IP addresses is crucial for network administrators and individuals working with computer networks.
