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 class=""></o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class=""><o:p class=""> </o:p></div><div style="margin: 0cm 0cm 0.0001pt; font-size: 11pt; font-family: Calibri, sans-serif;" class="">I’m surprised how little people/engineers really know about the fine works of NBN deployment.
