Which address translation scheme would allow a single public IP address to always correspond to a single machine on an internal network, allowing "server publishing"?

Overloading Port Address Translation (PAT) maps multiple private IP addresses to a single public IP using different port numbers, which does not provide a consistent one-to-one mapping for server publishing.

Dynamic Port Address Translation is another term for PAT or NAT Overload, mapping multiple private IPs to one public IP using port numbers, not a dedicated one-to-one mapping.

Dynamic Network Address Translation (DNAT) maps private IP addresses to a pool of public IP addresses on a first-come, first-served basis, meaning the public IP can change, which is unsuitable for consistent server publishing.

Static Network Address Translation (SNAT) creates a one-to-one, persistent mapping between a specific private IP address on the internal network and a public IP address. This fixed mapping allows external users to consistently connect to a specific internal server using its dedicated public IP, which is essential for 'server publishing' or hosting services accessible from the internet.
