Which technology separates IP addresses into two sets to hide the internal network layout and forces connections to go through a choke point?

• A. Network Address Translation
• B. Honeytrap
• C. Application-Level Proxy
• D. Low-Interaction Honeypots

Answer: (A)

Separating internal hosts from the outside world by hiding internal addresses and routing all traffic through a single gate is what Network Address Translation does. Inside the network, devices use private IPs that aren’t routable on the public Internet. The NAT device translates those private addresses (and ports, if needed) to one or more public IP addresses when traffic goes out, and does the reverse for responses. This creates two address sets—private and public—and makes the internal layout invisible to external observers. Because every external connection must pass through the NAT gateway, it also serves as a choke point where you can enforce rules and monitor traffic. Honeypots and honeynets are deception tools meant to attract attackers, not to separate address spaces or create a controlled boundary. An application-level proxy sits at the application layer and routes traffic through itself, which can centralize control, but NAT is the classic mechanism for concealing internal IPs and enforcing a network boundary at the IP level.
