    Network Address Translation – A Black Mark on IPv4’s Name

    Why do people use Network Address Translation?
    Because they always have, that’s why. “That’s the way we’ve always done it” is one of the dumbest reasons we do things. It precludes continued thought and absolves us the responsibility to think about why we are doing something. Network Address Translation (NAT) has been a bellwether of the Internet world for so long that many of us can’t remember a time without it. Many in the business rally around its role as a mechanism of security in our networks, “hiding the internal network” from the outside world. When presented in such a light it certainly sounds compelling. Being hidden from the evil, nasty outside world? Yeah! I-want-to-go-to-there.
