I allocate 8 bytes for the string inside sprintf, 12 for the ip and 1 for the string terminator. This totals 21, so why is it talking about 20 bytes and 18 bytes ?
Valgrind is reporting the storage required correctly...

char *headers = malloc(buffer + 1);  // malloc allocates 20 bytes
sprintf(headers, " -r %s\r\n", ip);  // this is 18 bytes becoz sprintf adds a null byte at the end
