Does Aussie Broadband support IPv6?

Last Updated: Tuesday 27 Feb 2024

IPv6 is now automatically included in the following Aussie Broadband services:

Some services can have IPv6 enabled on request, which includes:

Please note: Currently, IPv6 is not available on OptiComm broadband services.

Technical details for the curious

We use DHCPv6 for both the WAN interface Globally Unique Address (GUA) IPv6 address, via the IA_NA option, and the delegated IPv6 Global Unicast /48 prefix via the IA_PD option for use on the LANs downstream of the residential router.

We also provide our IPv6 anycast DNS resolver addresses via DHCPv6, using the DHCPv6 DNS SERVERS option.

Acquiring the WAN IPv6 addressing, LAN delegated prefix and the DNS server addresses via DHCPv6 are the likely default for residential routers when they are IPv6 capable and enabled.

The anycast DNS IPv6 resolver addresses are:

  • 2403:5800:100:1::142 /, and

  • 2403:5800:1:5::242 /

It is preferable to acquire them from DHCPv6 however, just in case we need to change them in the future.

Reverse DNS delegation

Advanced residential users can set up reverse DNS delegation for their /48 prefix. For the moment, these reverse delegations will need to be updated if the /48 prefix we supply you with changes, which may occasionally occur as we manage our NBN CVCs. We provide notification of when these CVC changes will occur within the MyAussie® portal and Smartphone application, and you can have them sent to you via SMS and/or email if you enable those options under your Profile within “Outage Communication Preferences”.

What is IPv6? (Internet Protocol version 6)

IPv6 is the successor to the current standard used for the internet IPv4.

IP is an address on a network/internet. IPv4 has 3,706,452,992 public addresses. This may sound like a lot but when you add up all the computers, servers and devices plus large quantities that were sold to companies like apple and HP in the early days of the internet.

At this current point in time most of the IP addresses available have been used up and getting more is very costly and requires a lot of work to do.

IPv6 has 3.4×10^38 possible addresses to use. It is estimated there is not enough room on earth for the amount of devices to use all the addresses available.

IPv6 also has some new and advanced features that will improve the performance of the internet in many ways.

Why IPv6?

  • IPv4 addresses are running out, and to purchase more is very expensive due to their increasing scarcity.

  • The internet is starting to make big moves to support IPv6. Currently, it is estimated 25% of devices also support IPv6. The majority of these will be servers providing websites and service.
