Why each option
This question asks for the primary benefit of deploying private IPv4 address ranges within an organization's internal network.
Private IPv4 addressing by itself does not enable secure connectivity over the Internet; this requires protocols like VPNs or TLS.
Private IPv4 addressing allows internal network devices to communicate with each other using addresses that are not routable on the public internet. This inherently shields them from direct external access attempts, as internet routers will drop packets destined for private IP ranges, thus providing a layer of security by obscurity.
While private IP addresses provide connectivity, they don't inherently make it more 'reliable' between like devices compared to public IP addresses within a private network. Reliability is determined by network design and infrastructure.
Private IPv4 addresses are explicitly *not* routable over an external network (the public internet); they are designed for internal use only.
