    I have a small LAN which is currently running IPv4. IP addesses are
    assigned from a DHCP reservation list, and network communications are
    via an NAT Router to our ISP and then the net.

    With all the buzz about IPv6, I am starting to have a look at it.
    Frankly, it looks as if it is of no use internally at all. We have
    more than enough local addresses to do what we want. We are
    "unpublished" and are not hosting ANY websites or external servers
    (all that is done by our ISP).

    The only thing I see as eventually becoming an issue is that there may
    come a time when IPv6 is required for our internal client machines to
    communicate with some sites on the Internet.

    My initial thoughts were that merely getting a new router / gateway
    which supports IPv6 would do the trick, but now I am not so sure.

    I have done some googling, and the more I read, the more confused -
    and concerned - I am getting. Some say that NAT will no longer be
    required with IPv6. Frankly, I happen to like NAT as a form of
    security. The idea of having fully resovable IPv6 addresses for all of
    our machines - effectivly leaving them hung out to dry on the open
    Interent - sounds like a new form of "security hell" to me!

    I want my LAN PRIVATE, thank you very much. There are a limited number
    of machines in our facilty that have had their attack surface narrowed
    sufficiently to even consider allowing into the wild.

    So, being a total IPv6 noob, could someone either explain how I might
    approach this, or at least point me in the direction of a goo primer
    on the subject???

    Thanks in advance!
