IPv4 Address Shortage
Network Address (NAT) and Port Translation (NAPT) can be seen as a solution, at least temporarily
- Breaks the end-to-end model of IP
- When a new application is not NAT-friendly, NAT devices requires an upgrade
- Mandates that the network keeps the state of the connections
- When there are many servers inside that need to be reachable for outside, NAT becomes difficult
