A. B. C. D. E.AD.
IPV4 private IP space refers to a range of IP addresses that are reserved for private use within a network. These addresses are not routable on the public internet, and therefore, they cannot be used for communication outside the network. There are three ranges of private IP addresses as defined by RFC 1918: 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16.
The reasons to use an IPV4 private IP space are:
To enable intra-enterprise communication: Using private IP addresses within an enterprise network allows devices to communicate with each other without the need for public IP addresses. This helps to create a more secure network environment because private IP addresses are not publicly accessible.
To conserve global address space: The number of available IPV4 addresses is limited, and using private IP addresses can help conserve global address space. Private IP addresses are used only within a network and do not require registration with a regional internet registry (RIR), which frees up public IP addresses for use by other organizations.
NAT (Network Address Translation) is a technology used to map private IP addresses to public IP addresses for communication on the internet. While NAT can be used in conjunction with private IP addresses, it is not a reason to use private IP addresses.
Connecting applications and managing routing overhead are also not reasons to use private IP addresses. While private IP addresses can be used to connect applications within a network, this is not their primary purpose. Similarly, private IP addresses do not impact routing overhead, which is a measure of the number of hops or devices a packet must traverse to reach its destination.
Therefore, the correct answers to the question are A. to enable intra-enterprise communication and D. to conserve global address space.
