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?
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?
Suggested Answer: D Vote an answer
The ipconfig /all output shows the following:
IPv4 Address............ 192.168.0.74Subnet Mask............. 255.255.255.255Default 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.
