2degrees IP Addresses

What is an IP address?

IP stands for Internet Protocol. An IP address is like the postal address for your internet connection - it gives the internet a destination to send the information you request every time you load a website, receive an email or download a file.

An IP address is a unique sequence of numbers that gets linked to your computer or computer network’s online activity.

Can I get a Static IP address with my 2degrees broadband connection?

If you require a Static IP, you can request one.

Home Broadband customers can get a Static IP for $10 per month either by emailing us, or by calling our 2degrees Broadband Care team on 0800 022 022.

There is no extra charge for Business Broadband customers who should call our Broadband Care team on 0800 022 249 to request a Static IP address.

Does 2degrees support IPv6? What is it?

Yes, we do, thanks for asking and giving us the opportunity to get geeky!

IPv4 stands for Internet Protocol version 4; IPv6 stands for Internet Protocol version 6.

Internet Protocol is the underlying technology that helps us to connect our devices to the internet.

IPv4 has been in use pretty much since the dawn of the internet. However, it has a limited amount of addresses available and as more of the world’s population access the internet with at least one device, we need more addresses.

IPv4 utilises 32-bits for its Internet addresses, whereas IPv6 – the newer technology – utilises 128-bit addresses.

In real terms, this means that IPv4 can support 4,290,000,000 (4.29 billion) addresses, which is pretty impressive, but IPv6 can go a lot bigger: 340,282,366,920,938,000,000,000,000,000,000,000,000 internet addresses. We’re not running out of IP addresses any time in the next millennium.

Here’s an example of an IPv4 address:

And here’s an example of an IPv6 address:


As a 2degrees customer you’ll be automatically assigned an IPv6 address as well as an IPv4 address when you connect to the internet. 2degrees-supplied modems support IPv6 and have this feature enabled by default.

Changes to IP Addresses (CGNAT)

If you've heard mumblings about something called CGNAT, and you’re wondering what it is, read on.

Carrier Grade Network Address Translation or CGNAT is a new way of giving out IP addresses, that are private instead of public. Don’t worry, the way you use your broadband generally won’t change, so your browsing, streaming and social media will keep going as it does today. The only difference is that your internet connection will no longer have its own public IP address, but a private one instead. If you’re a bit more of a tech head, there may be some changes to be aware of, so keep reading.

Why is 2degrees using CGNAT?

Our IP addresses are a little thin on the ground (shocking I know, but there’s a world shortage) so we’ve moved to CGNAT to make sure we can keep offering IP address services.

Who does it affect?

If you’ve got a broadband connection with a Dynamic IP broadband connection (not a Static IP), then you’ll be moved to CGNAT. Customers with a Static IP are not affected.

Will my broadband service be affected?

Any service or outside connection that is designed to reach you via your device’s public IP address to communicate with your modem won’t work. You may also notice an impact in the below.

  • Multiplayer video games where you’re hosting a session/server
  • Website hosting
  • Services or devices that rely on port forwarding
  • Torrents will only be able to establish outbound connections
  • Internet-enabled devices that are reached by IP address (e.g. IP cameras/security cameras)
  • Remote access to home network storage, backups and remote desktop service
  • Services that rely on Dynamic DNS (DDNS)
  • VPN servers

Is it just a 2degrees thing?

No, other providers in New Zealand and abroad have taken this approach.
