A. B. C. D. E. F.C.
Automatic IP addressing in IPv4 is a feature that enables hosts to automatically configure IP addresses without the need for manual configuration or the use of a DHCP server. This feature is also known as Automatic Private IP Addressing (APIPA).
Out of the given options, the correct answer for automatic IP addressing in IPv4 is option C, which represents the 169.254.x.x IP address range. This range is reserved by the Internet Assigned Numbers Authority (IANA) for link-local addresses, which are automatically assigned to interfaces when no other IP address is available or configured.
Option A (10.1.x.x) and option B (172.10.1.x) both represent private IP address ranges that are typically used in private networks, but they are not used for automatic IP addressing.
Option D (196.245.x.x) is not a reserved IP address range and is not commonly used for any purpose.
Option E (128.1.1.x) is a valid public IP address range but is not used for automatic IP addressing.
Option F (127.1.x.x) is a reserved IP address range that is used for loopback testing and is not used for automatic IP addressing.
Therefore, the correct answer for automatic IP addressing in IPv4 is option C (169.254.x.x).
