In a wireless network with DHCP disabled, what IP address type must clients use?

1. Dynamic IP addresses

2. Static IP addresses

3. APIPA addresses

4. No IP address

The correct answer is: Static IP addresses

In a wireless network where DHCP (Dynamic Host Configuration Protocol) is disabled, clients must use static IP addresses to communicate with each other and connect to the network effectively. Static IP addresses are manually configured and remain constant unless changed by a network administrator. This configuration ensures that each device has a specific IP address that doesn’t change, allowing for reliable communication within the network. Dynamic IP addresses, on the other hand, are assigned by a DHCP server and would not be an option in this scenario since DHCP is not operational. APIPA (Automatic Private IP Addressing) addresses are automatically assigned by devices when they cannot connect to a DHCP server and typically range from 169.254.0.1 to 169.254.255.254. However, APIPA is not a suitable choice for a well-configured network where communication is required among clients that need defined addresses. The option of "No IP address" is not feasible, as devices need an IP address to communicate over a network, even if it is a static one.
