Python program to determine if the given IPv4 Address is reserved using ipaddress module

Given a IPv4 Address, the task is to determine whether it is reserved (i.e belongs to class E) or not.

What is class E?

IP addresses belonging to class E are reserved for experimental and research purposes. IP addresses of class E range from – This class doesn’t have any sub-net mask. The higher-order bits of the first octet of class E is always set to 1111.

Output : Not Reserved

Output : Reserved

To implement it, we will use the is_reserved method of ipaddress module of Python3.3.





# importing ip_address
# from ipaddress module
from ipaddress import ip_address
def reservedIPAddress(IP: str) -> str:
    return "Reserved" if (ip_address(IP).is_reserved) else "Not Reserved"
if __name__ == '__main__'
    # Not Reserved
    # Reserved


Output :
