Why QHostAddress().toIPv4Address() is different from inet_addr()?



  • Hello.

    On Windows, QHostAddress().toIPv4Address() returns IP representation that is a reverted representation inet_addr() returns. For example:

    @QHostAddress( "192.168.0.1" ).toIPv4Address() != inet_add( "192.168.0.1" )@

    Why is such difference? And what is a good way to get "native" IP address representation that i can pass to third-party libraries or API functions?



  • Probably so as to get the same result an big and little-endian machines. The MS inet_add() function looks to be different for different endianesses (from the docs).



  • read docks :)
    winsock takes in account different byte order of different network interfaces.
