Which function does the range of private IPv4 addresses perform?
Click on the arrows to vote for the correct answerA. B. C. D.
Private IPv4 addresses are used within a private network that is not directly connected to the Internet. Private IP addresses are not routable on the public Internet, so they can be used by multiple companies or organizations without conflict. The range of private IP addresses is defined in RFC 1918 and includes the following address blocks:
These private address blocks are reserved for use within private networks and are not assigned to any organization. The use of private addresses allows multiple companies to each use the same addresses without conflicts.
Option A is the correct answer, as it describes the function of private IP addresses. Option B is incorrect because private IP addresses are not used for direct connections from outside the enterprise network. Option C is also incorrect because NAT (Network Address Translation) is often used to allow hosts with private addresses to access the Internet. Option D is incorrect because private IP addresses do not enable secure communications to the Internet for external hosts.
