The image contains a task that asks to identify which of the following is NOT a valid IPv4 address:

A. 192.168.1.1
B. 255.255.255.0
C. 10.0.0.256
D. 172.16.0.1

Let’s go step by step.

An IPv4 address has four numbers separated by dots (like A.B.C.D).
Each number must be between 0 and 255 — no more, no less.
Why? Because each number represents 8 bits (a byte), and 8 bits can only hold values from 0 to 255.

Now let’s check each option:

A. 192.168.1.1 → All numbers are between 0 and 255 → Valid ✔
B. 255.255.255.0 → All numbers are between 0 and 255 → Valid ✔
C. 10.0.0.256 → The last number is 256 → Too big! ✘
D. 172.16.0.1 → All numbers are between 0 and 255 → Valid ✔

So, the only one that breaks the rule is C.

Final Answer:
C. 10.0.0.256
