D is correct.
A will only support 2 hosts;
B only 6 and C only 14. Watch out for the minus 2 in the host calculation!
Answer C creates 16 hosts on the subnet, but we lose 2 -- one for the NET ID and one for the Broadcast ID.

What if my subnet mask is not configured properly?

I know subnet mask is used to separate network byte and host byte but what if my subnet mask is not configured properly.

E.g.
In my environment i need to use 255.255.254.0 as a subnet but i mistakenly configured 255.255.252.0 but still I am able to receive and send data from my system, Then what is the use of using correct subnet?

UE IP subnet mask

IFconfig command on smart phone returns both the Mobile-IP and the subnet mask (using terminal Emulator)
The UE-IP is allocated by either the HSS (S6a-ULA) or the PGW (GTPv2C Create-Session response).
However, only the IP address is present in those messages and not the subnet mask.

My question is how the UE knows about the subnet mask?
Does it obtain from the PGW?
Is the UE aware about the PGW IP address?
