   Maybe each of those attributes should be an object of a
   special class where your "__to_str" is "__str__"? E.g.,

# code in "calcip.__init__"
self.tsubnet = ip_address_class.from_int( subnet )

   where "ip_address_class" is as in:

import collections
import random

class ip_address_class( collections.UserList ):
     def __init__( self, bytes_address ):
         super().__init__( bytes_address )
     @classmethod
     def from_int( cls, int_address ):
         return cls( int_address.to_bytes( 4, 'big' ))
     def __str__( self ):
         return '.'.join( str( byte_ )for byte_ in self.data )

if __name__ == '__main__':
     ip_address = \
     ip_address_class.from_int( random.randint( 0, 4294967295 ))
     print( ip_address[ 0 ])
     print( ip_address )

   . Now the client can access each byte individually and also
   get a "nice" string representation.

   (You may add more "from_..." methods for all the various
   formats you create addresses from.)

   But you should also research the standard library to see
   if something like this doesn't already exist ready-made
   specifically for IP addresses in the standard library.

ok. thanks a lot. now i try to do that.
