Question

You are not able to access the Internet using your laptop. Your laptop has the following configuration: IP Address. . . . . . . . . . . . : 10.0.0.230 Subnet Mask . . . . . . . . . . . : 255.255.255.255 Default Gateway . . . . . . . . . : 10.0.0.225 Why can't you access the internet?

A. The subnet mask is misconfigured.
B. The DNS server is misconfigured.
C. The gateway is misconfigured.
D. The IP address is misconfigured.

Answer 1

C. The gateway is misconfigured. The inability to access the internet is likely due to a misconfigured subnet mask of 255.255.255.255, which prevents communication on the local network. Changing the subnet mask to 255.255.255.0 should resolve the issue, allowing access to the default gateway.

Step-by-step explanation:

The reason you are not able to access the Internet using your laptop could be due to a misconfigured subnet mask. The subnet mask you have provided, 255.255.255.255, means that your device is not allowed to communicate with any other devices on the local network, which includes the default gateway. Typically, a subnet mask for a small network would be something like 255.255.255.0, allowing communication with other devices within the same subnet.

To correct the issue, you should reconfigure the subnet mask to a proper value that allows network communication. For example, if the intended network is a small local network, setting the subnet mask to 255.255.255.0 should permit the laptop to communicate with the default gateway and access the Internet, provided the other settings (IP address and default gateway) are configured correctly.
