Introduced init_random function to seed the random number generator once, enhancing the randomness of IP addresses when random_ip is called frequently.
Defined IP_STR_LEN constant to replace the magic number 20, clarifying the intent behind the buffer size for the IP address string.
Added error checking for malloc to handle potential memory allocation failures, preventing undefined behavior from a NULL pointer dereference.
Documented the caller's responsibility to free the memory allocated by random_ip to aid in preventing memory leaks.
Removed non-standard header <bits/types/struct_timespec.h> and relied on the standard <time.h> for better code portability.
Adjusted the allocated buffer size to 16 bytes, which is the exact size needed for a null-terminated IPv4 address string.
Cast the seed to unsigned int for srand to match the expected data type, ensuring consistent behavior across different platforms.
