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 or PPPoE. When we create a static IP for you, your router settings do not need to change – you get a static DHCP lease or static IP via PPPoE. (Vumatel Active Ethernet 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
- You can’t host a DNS server on your static IP, we filter outgoing UDP port 53 (DDoS reasons)
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
