In the DHCP example for 192.168.20.0/24, what is the gateway address for clients?

• A. 192.168.20.1
• B. 192.168.20.254
• C. 192.168.20.2
• D. 192.168.21.1

Answer: (A)

The gateway is delivered to clients through the DHCP Router option, which specifies the default route they should use to reach networks outside their local subnet. For the 192.168.20.0/24 network, the example is set so the gateway is the first usable address, 192.168.20.1. Because DHCP hands out this value as the default route, clients automatically route non-local traffic through 192.168.20.1 to reach other networks and the internet. The other addresses shown don’t match the gateway in this scenario: 192.168.20.2 is simply another host address, 192.168.20.254 is not designated as the gateway in this example, and 192.168.21.1 would belong to a different subnet.
