1. Which of the following is not a valid IPV4 Address?
- A. 10.11.12.13
- B. 10.11.12.13
- C. 10.11.12.13
- D. 10.11.12.13
Answer: Option D
Explanation:
The invalid IPv4 address is 4. 10.145.12.256 because an IPv4 address octet cannot exceed 255, and the last octet in this address is 256.
Explanation:
An IPv4 address consists of four octets (numbers separated by dots), each ranging from 0 to 255.
In the given options, only the fourth address (10.145.12.256) has a last octet exceeding the allowed limit of 255.
Why other options are valid:
1. 10.11.12.13: This address falls within the valid range for IPv4 addresses.
2. 156.145.197.169: This address is also a valid IPv4 address.
3. 172.16.17.0: This address is a valid IPv4 address as well.
