IPChecker is a tiny Python library that is used to check if an IP version address is Private, Public or Invalid,
The library returns Booleans and contains a couple of methods summurized as follows:

isValid(): This method returns True, if a valid IPv4's given, otherwise, it returns False.
isPrivate(): This little method returns True if the given IP is private, otherwise, False is returned.
isMCast(): This little method returns True, if a Valid IPv4 is given and it's among the multicast ip range, otherwise, it returns a False.
isPublic(): This little method returns True if the given IP is a Valid IPv4, not private and not multicast address, otherwise, False is returned.

Usage:
>>> from IPChecker import IPChecker
>>> obj = IPChecker("172.16.122.254")
>>> obj.isValid()
>>> True
>>> obj.isPrivate()
>>> True
>>> obj.isMCast()
>>> False
>>> obj.isPublic()
>>> False

Here is a sample grabbed from the IPchecker source code given as an example of how you can checkout for a valid IPv4 address using regular expressions.

in this example, the built-in python re module is used.

>>> def isValid(self):
>>> ____if findall( "(?i)^(\d|\d\d|1[0-9][0-9]|2[0-4][0-9]|25[0-5]).(\d|\d\d|1[0-9][0-9]|2[0-4][0-9]|25[0-5]).(\d|\d\d|1[0-9][0-9]|2[0-4][0-9]|25[0-5]).(\d|\d\d|1[0-9][0-9]|2[0-4][0-9]|25[0-5])$" ,self.IP):
>>> ________ return True
>>> ____else:
>>> ________ return False
