What is the range of values for each Octet in an IP Address?

An IP address is composed of four octets, and each octet represents an 8-bit binary number. The range of values that can be represented by an 8-bit binary number spans from 0 to 255. This is derived from the fact that with 8 bits, there are (2^8) (or 256) possible combinations, which correspond to decimal values ranging from 0 to 255.

Therefore, in the context of an IP address, each octet can only take on values within this range, making it essential for networking and routing protocols that rely on these standard formulations. The other ranges provided would not accommodate the full potential of an octet and would thus be inaccurate representations of the range of values for each octet in an IP address.
