How does Dynamic PAT (Port Address Translation) handle IP address translation for a large number of internal hosts?
- It assigns a unique public IP address to each internal host.
- It dynamically assigns unique port numbers to each internal host sharing a single public IP address.
- It relies on static port assignments for each internal host.
- It uses multiple public IP addresses in a one-to-one mapping with internal hosts.
