Question

A user reports that a device with a statically defined IP is unable to connect to the internet. The technician runs the ipconfig /all command and sees the following output:

IPv4 Address............ 192.168.0.74 Subnet Mask.............255.255.255.255 Default Gateway......... 192.168.0.1 Which of the following is most likely the reason for the issue?

Options

  • AThe default gateway is up.
  • BThe user has an APIPA IP address.
  • CThe IP address is on the wrong subnet
  • DThe subnet mask is incorrect.

Explanation

The ipconfig /all output shows the following: IPv4 Address............ 192.168.0.74 Subnet Mask............. 255.255.255.255 Default Gateway......... 192.168.0.1 The issue with the subnet mask being set to 255.255.255.255 is that it specifies a single host subnet, meaning the device cannot communicate with other devices on the network or access the internet. The correct subnet mask for a typical home network should be: Subnet mask of 255.255.255.0: This allows for communication within the same local network (192.168.0.0/24). Default gateway 192.168.0.1: Correct, this is the typical address for the router. IPv4 Address 192.168.0.74: Correct, within the correct subnet range. Changing the subnet mask to 255.255.255.0 will resolve the connectivity issue.
