> 2. Do you use a home ISP connection, or a commercial ISP connection? A "home ISP connection" here usually comes with a dynamic IP address; you can't get your hands on a static address without paying a very large amount monthly or getting a commercial connection.

Weirdly, most of the ISP's I've had on the NBN here in Australia were happy to give me a static IPv4 address for free (and my current one will set you up an IPv6 /56 block, but its beta apparently).
