Explanation
Private IPv4 addresses, such as those in the ranges 10.0.0.0/8, 172.16.0.0/12, and 192.168.0.0/16, are not globally unique and are not routable on the public internet. By using private IPv4 addresses within an organization’s internal network, the need for public IPv4 addresses is reduced, helping to alleviate the shortage of available public addresses.
Moreover, private IPv4 addresses offer a layer of security by not being directly accessible from the internet. Since these addresses are not routable on the public internet, devices using private IPv4 addresses are not directly exposed to external threats, such as unsolicited connections or attacks originating from the internet. This inherent isolation provides an additional level of protection for an organization’s internal network resources.
