Correct option is A
202.54.256.30 is not a valid IP address because it contains 256 in the third octet, which is outside the valid range of 0 to 255 for IPv4 addresses. Each section of an IPv4 address must be a number between 0 and 255.
Important Key Points
1. IPv4 addresses consist of four octets, with each number ranging from 0 to 255.
2. Private IP addresses (like 10.10.10.120) are used within local networks.
3. IP addresses are essential for identifying devices on a network.
