Get a static IP address for your Fibre Internet

We offer a static IP address service, or multiple static IP addresses, on our Home and Business Fibre Internet services on Octotel, Frogfoot, Vumatel and Openserve. The methods to implement a static IP can be different depending on which network you are on.

Your router will always be assigned the same IP address. Static IP addresses are assigned from a different IP pool than our dynamic IP pool and your static IP(s) are reserved just for you.

⚠️ Please never configure your router WAN port to have a static IP config. When we create a static IP for you, your router settings do not need to change.

Static IP address options (IPv4)

  • 1 static IP /32
  • 8 static IPs /29 (5 usable normally)
  • 16 static IPs /28 (13 usable normally)

Pricing is on the relevant fibre network page, and on the change request form.

Order static IP(s)

Please use our change request form to order a static IP address. You will need your service ID (on your invoice).

Caveats

  • If you move fibre network you will not be able to keep the same static IP address
  • IP space is routed to a single fibre line, it is not possible to use a /29 or /28 across multiple sites
  • If you change your router, please let our support team know, as we may need to update the MAC address the static IP is linked to

How to add a /29 network (traditional routing)

  • You’ll need an existing static IP config for your router’s WAN port, linked to the MAC address or via PPPoE config
  • Keep the WAN side of your router config the same (no change needed). Do not set this to ‘Static IP’.
  • We’ll route the /29 network to the static IP on your WAN port
  • The 1st usable IP in the /29 is actually the 2nd IP, you can’t use the ‘network’ or ‘broadcast’ addresses. Please do a web search if this is unfamiliar.
  • Give the router LAN port the 1st usable IP in the /29 network, with subnet mask 255.255.255.248
  • Now assign the other IPs in the /29 to devices on your LAN, and give them a gateway of the 1st IP in the /29 which is on the router’s LAN port. Make sure you give them the correct netmask.
  • You’ll also need to configure DNS servers for these devices, or you can just use something like 9.9.9.9
  • Adding a /28 network is similar, but the netmask is different (255.255.255.240)

How to add additional IPs with DNAT

  • You will need an advanced router or firewall, a basic home router will probably not support this
  • This method can give you more usable IPs and can be more secure, but will be more complex to configure and maintain
  • You’ll need an existing static IP config for your router’s WAN port, linked to the MAC address or via PPPoE config
  • Keep the WAN side of your router config the same (no change needed). Do not set this to ‘Static IP’.
  • We’ll route the additional IPs to the static IP on your WAN port
  • Bind the additional IPs to the router, usually to the loopback interface
  • Now set up DNAT (Destination Network Address Translation) rules to map the additional public IP to a private IP on the LAN
  • Give your servers or services private IPs on the LAN, usually something like 10.n.n.n
  • Each firewall or router will have its own configuration model for IP and Port mapping using DNAT
