The inet_ntoa() function C returns the address of a client side, for example. The programmer does not have to explicitly declare the type of variable; rather, the Python interpreter decides the type of the variable and how much space in the memory to reserve. The Python socket library has utilities to deal with the various IP address formats. To increment an IP address you will need to break up the in_addr object into 4 int objects (a short int will also do) and increment the 4th one until it hits 256, and then reset it to 1 and increment the 3rd one, etc. Let … - Selection from Python Network Programming Cookbook - Second Edition [Book].
