What is the key difference between a static IP and a dynamic IP?

• A. A static IP remains constant; a dynamic IP is assigned by a DHCP server and can change.
• B. A static IP changes frequently; a dynamic IP never changes.
• C. Static IPs require NAT; dynamic IP does not.
• D. Static IPs are for IPv6; dynamic for IPv4.

Answer: (A)

The key idea is address stability. A static IP stays the same for a device, set manually or reserved so it won’t be reassigned. A dynamic IP is given by a DHCP server and can change over time as leases expire or devices reconnect. This matters in a simulator network where you need reliable access to a machine or service; using a static IP means other devices or users can always reach that endpoint at the same address. With a dynamic IP, you’d have to track any changes and update connections accordingly, which adds management overhead. The other statements don’t fit because NAT is not a requirement of static IPs, and IPv6 can be assigned statically or dynamically the same way as IPv4; choosing between static and dynamic isn’t about IPv4 versus IPv6.
