Which method will allow you to use RFC 1918 addresses for Internet requests?

Network Address Translation (NAT) was created to slow the depletion of Internet addresses. It does this by translating RFC 1918 privatized addresses to one or several public IP addresses. It allows the packets to masquerade as the public IP address on the Internet until it is translated back to the private IP address. Classless Inter-Domain Routing (CIDR) is a notation used to express the network for a host. Classful addressing is the original addressing scheme for the Internet. Virtual private networks (VPNs) are used for remote access.
