    You are correct, from what I have heard. They 'Police' the link
    rather than 'Shape' the link, i.e. once the AVC limit is reached
    (12/1, 25/5 etc), the packets on top are dropped rather than queued
    for delivery. This means NBNCo's routers would have to do a lot less
    work, so to avoid packet loss, dropped packets etc for customers who
    max out their link it is a good idea to do queuing on your own
    termination end.<br>

        <p class="MsoNormal"><o:p> </o:p></p>
        <p class="MsoNormal">Quick question about the NBN deployment. I
          am looking for a technical answer here. Some NBN services give
          you a public IP via DHCP and they push a default route with
          it. How are the customers separated and how is the same IP
          leased to the same NBN endpoint every time? Is this something
          that is different from ISP to ISP or? There is no auth on the
          endpoint, and it can’t be the MAC either.<o:p></o:p></p>
        <p class="MsoNormal"><o:p> </o:p></p>
        <p class="MsoNormal">I’m surprised how little people/engineers
