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 for implementing a static IP can differ depending on which fibre 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.

⚠️ As a general rule, please never configure your router WAN port to have a static IP config on the WAN port – keep it on DHCP. When we create a static IP for you, your router settings do not need to change – you just get a static DHCP lease. (Vumatel AE is an exception, but we’ll communicate how this works when you order a static IP on Vumatel AE.)

Extras #

• If you buy a static IPv4 service, we can also configure static IPv6 for you
• We can set up DNS PTR (reverse) records for customers with static IPs (IPv4 and IPv6)

Static IP address options (IPv4) #

• 1 static IP /32
• 8 static IPs /29 (5 usable normally) – not available on Vumatel AE

Pricing is on our 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 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

If you would like to know more about IPv6, please see our IPv6 help doc: https://www.atomic.co.za/docs/ipv6/

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

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
