This code is not endian-dependent. You can only observe endianness when you address the same memory as two different types:

    int x = 5;
    char *chp = (char*)&x;
    printf("This value is endian-dependent: %hhd\n", *chp);

The code isn't endian-dependent because it doesn't do anything. The only thing you can do with "3232235777" on a little-endian machine is compare it to another number to see if it's also "3232235777".

If you're going to store IP addresses as 32 bit integers, or work with them that way in your C code, 192.168.1.1 should be "16885952", so you can do > and <.

But your point is well taken, and audiguy, I'm sorry for being such an asshole in my comment.

ip addresses are always stored in network-byte-order

Your ALU doesn't care what the RFC says. What's the point of storing addresses in binary if you can't do math on them? There is no point, is the point.
