A lot of people are adding padding when they need to store IPs. So they can be easily sorted using alphanumeric sort:
192.168.001.001 192.168.001.002 192.168.001.003 ... 192.168.001.254
And then use it that way to connect to servers, causing lots of confusions.
In [2]: socket.inet_aton('226.000.000.037')
Out[2]: b'\xe2\x00\x00\x1f'
In [3]: socket.inet_aton('226.000.000.37')
Out[3]: b'\xe2\x00\x00%'
In [4]: socket.inet_ntoa(b'\xe2\x00\x00\x1f')
Out[4]: '226.0.0.31'
In [5]: socket.inet_ntoa(b'\xe2\x00\x00%')
Out[5]: '226.0.0.37'I.. wow.
