What is the maximum value of any octet in an IPv4 address?

Explanation:
In an IPv4 address, each octet is an 8-bit number, which means it can represent values ranging from 0 to 255. This is because an 8-bit binary number can have \(2^8\) or 256 possible values, starting from 0. Therefore, the maximum value that can be represented by any octet in an IPv4 address is 255. The other options do not reflect this maximum. For instance, 256 exceeds the range of an 8-bit binary representation, and both 128 and 512 fall outside the possible values for an octet in the context of IPv4 addressing. Hence, 255 is indeed the highest valid value for an octet in an IPv4 address.
