Explanation

Private IP addresses (defined by RFC 1918: 10.0.0.0/8, 172.16.0.0/12, 192.168.0.0/16) have two key properties: (C) They are NOT globally unique-the same private address ranges can be reused across thousands of different private networks simultaneously, which is why NAT is required for internet communication; and (B) They are considered more secure than public IP addresses because they are not directly reachable from the internet, requiring a NAT gateway or VPN for external access. Option A is false-private IPs cannot directly access the internet. Option D is false-within the same local network, each device must have a unique private IP. Option E is false-private ranges are managed locally, not by a global registry like IANA.
