The below guides are there to assist you in setting up IPV6 on your router. We have tested the settings on these models in our office and confirmed that they work. Please be aware that most guides below are for routers that we haven’t supplied or no longer supply. If you have issues with IPv6 and need further help we recommend you contact your router’s manufacturer.

Why do we need IPv6?

• Running out of IPv4 addresses – the world is running out of address space on the older protocol and we need to switch to something larger.
• Remove multiple layers of NAT. Currently, the way we get around the shortage of IPv4 addresses is by using Network Address Translation (NAT) to hide private addresses behind a public address and have a device translate between the two. This has limitations that can cause problems with some games, virtual private networks (VPNs) and some business applications, especially voice. IPv6 does not have NAT as we are able to have enough address space for every single device to have its own.

What does Leaptel provide?

Leaptel has been trailing IPv6 access since early 2022. Our network is built as a dual-stack environment (so both IPv4 and IPv6 together) and Customers have been able to enable IPv6 via the members portal via an opt-in process. Each customer who enables the service is:
- Allocated Global Unicast Address for their router connected to the internet
- Allocate a /56 delegation for their router to use to allocate addresses to their entire household. That is 4,722,366,482,869,645,213,696 addresses per customer.

We support IPv6 on:
- NBN Customers connecting via PPPoE or IPoE.
- Opticomm customers connecting via PPPoE or via IPoE (in areas in which Opticomm’s infrastructure supports it).
- Lightning Wholesale areas via PPPoE.

How does IPv6 work?

Once your router has connected up IPv4, your router will then make a DHCP request for IPv6. At that time we will provide your router with:
- A global unicast IP address for the routers network port to us
- A /56 Prefix delegation for your router to make ipv6 work within your home network.

What then happens is your router will take the /56 delegation and in a normal home situation it will then allocate one /64 subnet from that delegation to your local network and begin making that address space available to your devices.

Is there any security issues with a public address being assigned to my devices?

No. The default configuration of most IPv6-capable residential routers will have a firewall protecting your devices from the public internet. In addition to this most devices also have their own firewall to provide another level of protection.

Many devices will also randomise the address they use to ensure that the device keeps moving around making it difficult to predict the address your device will have providing you with another layer of protection.

I have a static IPv4 address, can I get a static IPv6 allocation?

Not yet, we are hoping to have this working by early 2023.

What is my prefix delegation size?

Leaptel will return a /56 prefix delegation when you request IPv6.

Why is IPv6 not available on my OptiComm address?

The equipment OptiComm has installed at some locations is old and is not capable of correctly providing the Option 82 injection of your service ID to allow us to authenticate your connection. Once OptiComm upgrades the network infrastructure you will be able to get IPv6 at addresses that currently cannot.

When you go to turn on IPv6 we run a check with OptiComm to confirm if it is available and if it is not we cannot enable the protocol for you.

What DNS servers should I use?

We would prefer you to obtain your DNS servers from DHCP however if you need to statically allocate DNS servers our servers are on our DNS page.

DHCPv6-PD, SLAAC? What do I need?

Leaptel uses DHCPv6-PD (Dynamic Host Configuration Protocol version 6 with Prefix Delegation) to obtain an IPv6 Global Unicast address and a Prefix to use for your local network.

SLAAC (Stateless Address Autoconfiguration) is not used by us however it is then commonly used by your router to then provide IPv6 within your local network combined with DHCPv6 to then provide DNS details. You can find information on what SLAAC is and how it works here

Do I need a tunnel to run IPv6?

No, Leaptel does not use any tunnelling to support IPv6. We run a Dual Stack environment.

My router has an ipv6 address beginning with FE80, am I connected?

No. Addresses beginning with FE80 are what is called a link-local address which only provides IPv6 connectivity to devices on the same local network. Every device on an IPv6 network will normally have 2 addresses, a link local and then a global unicast address which on the Leaptel network begins with 2402::.

Do I have to get a Global Unicast address on my wan port of my router? Can I just get a prefix delegation?

No, it is not required that you get a Global Unicast Address. You can just request just a prefix delegation from our BNGs. This will work if your router is capable.

I have a old router I am currently using an access point to extend my network? Can I use IPv6?

Yes but you need to be careful to ensure that both dhcpv4 and dhcpv6 are turned off on your access point and that you are connecting the LAN ports of your access point to the LAN ports of your router.

If you don’t do this your access point will try and request a prefix from your router which will go unanswered and will cause you issues as well as you could have the access point incorrectly returning to devices that it is also a router and break IPv6 from working.

How can I test if IPv6 is working?

Easiest way is to visit and confirm that it says the IPv6 is supported
