Why each option
Private IPv4 addresses are designated for internal network use and are assigned by an organization's network administrators to devices within their private network.
Private IP addressing itself does not enable secure connectivity over the internet; that requires additional security mechanisms like VPNs or encryption.
Private IP addresses are not routable across external internet boundaries; they require Network Address Translation (NAT) to communicate with public internet resources.
Private IPv4 address ranges, defined in RFC 1918, are reserved for use within private networks and are typically assigned by an enterprise or network administrator to internal hosts that do not require direct internet routability.
Private IPs are used by end-user organizations for their internal networks, not by ISPs for connecting to the internet, which typically uses public IP addresses.
