How Python converts IP addresses to integers

The example in this article describes how Python translates IP addresses into integers. Share to everyone for your reference. The specific analysis is as follows:

Sometimes when we use the database to store IP addresses can be converted to integer storage IP address, integer occupies a small space, the index will be more convenient, the following Python code to customize a function of IP conversion to integer, very simple, the code also provides a method of converting integers to IP addresses.

Import socket, structdef Ip2long (IP): "" "  Convert a IP string to Long" "  Packedip = Socket.inet_aton ( IP)  return struct.unpack ("! L ", Packedip) [0]

For example, the IP address of www.jb51.net is: 61.129.51.27, call the Ip2long conversion function above:

Print (' www.jb51.net IP address is%s '%ip2long (' 61.129.51.27 '))

The output is:

Www.jb51.net IP Address is 1031877403

If you want to convert an integer to an IP address, you can use the following method:

Socket.inet_ntoa (Struct.pack ('! L ', 2130706433))

The output is:

' 127.0.0.1 '

Hopefully this article will help you with Python programming.
