Which two goals reasons to implement private IPv4 addressing on your network? (Choose two)

While PCI DSS (Payment Card Industry Data Security Standard) requires network segmentation and security, the use of private IP addresses specifically is not a direct compliance requirement, though it contributes to overall network security.

Private IPv4 addresses (defined in RFC 1918) are non-routable on the internet, allowing organizations to reuse the same address ranges internally without needing to register them, thereby conserving globally unique public IPv4 addresses.

Private IP addressing itself does not directly reduce the size of forwarding tables on network routers; rather, it allows for summarization and NAT at the border, which can indirectly affect table size, but conservation and security are primary direct goals.

By using private IP addresses in conjunction with Network Address Translation (NAT), internal hosts are hidden from the public internet, making them less susceptible to direct attacks and reducing the risk of a network security breach from external sources.

The use of private IP addresses is a networking best practice and a technical choice, not a mandate for compliance with local laws, which typically focus on data privacy or telecommunications regulations.
