If you can access it - it's not broken. There are plenty of tools to
monitor your VMs networking.

Optus provide multiple APNs - perhaps you need to try another APN for
IPV6 support (call Optus support). Alternatively check your phone's
configuration (not all phones support IPV6). In my experience Telstra
only gives IPV6 to NBN and Business accounts.

Whirlpool page on ISP support for IPV6 in Australia

IPV6-test results page:-

Test your IPV6 capability:-

IPV6.org.au try IPV6 page:-

Most government departments I'm familiar with have moved to IPV6 -
perhaps your experience with ACT schools is due to a local LAN
configuration (not my understanding). Perhaps because some people equate
NAT with security (there's an ARP joke there somewhere)?

Note for others - "ip a" will show network details, if you have IPV6
enabled you'll see an IPV6 address e.g.:-
3: wlp2s0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 qdisc mq state UP
group default qlen 1000
    link/ether 00:22:fb:c4:6d:04 brd ff:ff:ff:ff:ff:ff
    inet brd scope global dynamic wlp2s0
       valid_lft 2532sec preferred_lft 2532sec
    inet6 fe80::f93:8ed:dbd6:813c/64 scope link
       valid_lft forever preferred_lft forever

In this case the inet6 address starts with "fe", which means it does
*not* support IPV6 internet (nor do addresses starting with "::", "fc",
or "fd")

Kind regards
