The correct answer and explanation is:
Here are the correct matches between the IP address descriptions and the provided options:
- A link-local address: 169.254.1.5
- A public address: 198.133.219.2
- An experimental address: 240.2.6.255
- A loopback address: 127.0.0.1
Explanation
1. Link-Local Address (169.254.1.5):
Link-local addresses are automatically assigned to devices when no DHCP server is available, and they belong to the range 169.254.0.0 to 169.254.255.255. These addresses are used for communication between devices on the same physical or logical link, such as when two computers are connected via a crossover cable.
2. Public Address (198.133.219.2):
Public IP addresses are globally routable on the internet and are assigned by the Internet Assigned Numbers Authority (IANA) or Regional Internet Registries (RIRs). The address 198.133.219.2 is not part of any reserved ranges (e.g., private, loopback) and is classified as a public address.
3. Experimental Address (240.2.6.255):
Addresses in the range 240.0.0.0 to 255.255.255.254 are reserved for experimental use. They are not assigned for any specific public use and are not routable on the global internet. The address 240.2.6.255 falls within this experimental range.
4. Loopback Address (127.0.0.1):
Loopback addresses are used for testing purposes and interprocess communication on the same host. They are assigned to the range 127.0.0.0 to 127.255.255.255, with 127.0.0.1 being the most commonly used address. This address routes traffic back to the same device, ensuring that network configurations and services are functioning correctly.
The address 172.18.45.9 is not used in this question, but it belongs to the private IP address range (172.16.0.0 to 172.31.255.255).
