Which of the following IP addresses is invalid due to an octet exceeding 255?

IPv4 addresses use four octets, and each octet must be in the range 0 to 255. An octet value of 256 is not representable in 8 bits, so any address containing 256 in any position is invalid. In the given set, the address with the third octet as 256 (22.131.256.3) breaks this rule, making it invalid. The other addresses have all octets within 0–255, so they are valid.
