IP addresses are the “phone numbers” of the Internet – a unique identifier used to ensure that the traffic from point A (for example, a Netflix server) can get to point B (for example, your laptop) accurately and efficiently. Historically, IP version 4 (“IPv4”) has been used successfully to run the internet, but with available addresses nearing depletion due to limitations with how many unique addresses can exist using IPv4, the time has come for a new system – IPv6.
IPv6 is crucial to the future of the internet, with IPv4 addresses scarce and expensive, today’s internet needs to run IPv6 everywhere sooner rather than later. IPv4 space is terribly finite and procuring more just isn’t feasible. While we continue to investigate and evaluate strategies to extend our IPv4 resources, IPv6 represents the immediate future of the internet.
Retrofitting IPv6 into an existing ISPs network brings a lot of challenges, it’s just not as simple as turn it on and away it goes – there are many challenges to consider: modem/router compatibility, authentication systems, assigning addresses to thousands of existing services, BNG support, the list goes on. A startup ISP can enable IPv6 without these considerations.
While our Anycast (AS58511) backbone network has been the most connected IPv6 network in Australia for many years now, it’s excellent that we can finally announce that all DCSI customers, old and new, can enable IPv6 from right now.
In less than 2 years since we acquired DCSI, we have faced some significant network challenges; including growing and upgrading the fixed wireless network, replacing the third-party billing system with our own system and new customer portal, and now finally – IPv6 for everyone.
We are not done yet though – even once we deliver IPv6 to all our DCSI customers we have many more upgrades and changes to come. We will continue the tradition of DCSI innovating for our customers on both our NBN and fixed wireless networks!
The technical stuff –
Our IPv6 deployment uses DHCPv6 Prefix Delegation to give every customer service a /56 IPv6 prefix – that’s 256 subnets of 18,446,744,073,709,551,616 addresses each. To enable IPv6 on your connection, all you have to do is enable it on your modem/router, and the network will take care of the rest.
We have also elected to continue to use PPPoE for our customers – PPPoE allows some specific features that are unavailable via IPoE, such as enhancements to FTTN connections specific to Australia’s NBN.
IPv6 can be used on all DCSI broadband services: NBN, Fixed/Acceler8d Wireless, Fibre Connect and ADSL.
