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 PAT multiplexes many internal hosts to a single public IP differentiated by port numbers, which is a many-to-one translation and cannot guarantee a consistent single-host binding needed for inbound server publishing.

Dynamic PAT also maps multiple private addresses to one public IP via port tracking on demand and does not provide the stable one-to-one binding required to reliably publish an internal server.

Dynamic NAT assigns public IPs from a pool on a first-come basis, meaning the public address assigned to a given internal host can change between sessions, making consistent inbound server access impossible.

Static NAT permanently binds one specific public IP address to one specific private IP address, ensuring that all inbound traffic destined for that public IP is always forwarded to the same internal server; this deterministic and unchanging mapping is the requirement for reliably hosting public-facing services such as web, mail, or DNS servers.
