Answer:
You can setup firewall rules with for example iptables on Linux. The rules should block source addresses of private IP ranges such as 192.168.*.* and 10.*. *. * etc. Check private IP ranges for full list.
It will however not guarantee prevention of IP spoofing in general as its not possible to prevent such attacks. Its the responsibility of ISPs. But the question asked for private IP spoofing and then the above works.
Answer:
10.5
Explanation:
1010.1
Handy method you can find searching google images, and I originally learned
from some guy teaching an online java course.
.1 --> 1 * 2^(-1) = 0.5
0 --> 0 * 2^(0) = 0
1 --> 1 * 2^(1) = 2
0 --> 0 * 2^(2) = 0
1 --> 1 * 2^(3) = 8
0.5 + 2 + 8 = 10.5
If for some reason it isn't very clear, just take the number, (x) and multiply it
by two to the power of the position it is in. (e.g. first number before decimal point is 0, second 1, etc).
Foreshortening is the visual effect or optical illusion that causes an object or distance to appear shorter than it actually is because it is angled toward the viewer. Additionally, an object is often not scaled evenly: a circle often appears as an ellipse and a square can appear as a trapezoid.
Answer:
def is a keyword used to define a function, placed before a function name provided by the user to create a user-defined function
__init__ is one of the reserved methods in Python. In object oriented programming, it is known as a constructor. Python will call the __init__() method automatically when you create a new object of a class, you can use the __init__() method to initialize the object’s attributes.
Example code:
class Person:
def __init__(self, name, age):
self.name = name
self.age = age
p1 = Person("John", 36)
print(p1.name)
print(p1.age)
Summary
- Use the __init__() method to initialize the instance attributes of an object.
- The __init__() doesn’t create an object but is automatically called after the object is created.
