How Superloop manages internet addressing & routing


How Superloop deploys IP Address Space

Superloop has a long-term strategy view in the methodology of IP address allocation on our network. We are active in the network community in promoting IPv6 adoption while still providing options for legacy software and equipment.

Superloop allocates CGNAT IPv4 addressing for our consumer users and Publicly accessible IPv4 addressing for our Corporate users.

What is CGNAT IPv4?

CGNAT or Carrier Grade Network Address Translation is a method of providing special use IPv4 addresses to End Users on our network which are translated to Public address space in our core network. CGNAT a method of continuing to provide IPv4 addresses even after the exhaustion of IPv4 address space from regional Internet Registries such as APNIC. Carrier Grade NAT is fast, efficient and is designed to handle the considerable processing requirements of the devices on our network.

Superloop allocates dynamic CGNAT IP Addressing in the Shared Address space of as per IETF RFC 6598. As such unestablished external access to devices is not possible nor can hosting of Internet accessible services be undertaken. In some locations, Superloop offers static directly accessible IPv4 public addressing.

Superloop has also deployed our network in our core to support IPv6 and is continuing to develop our edge and access networks for IPv6. We are registered with the World IPv6 Launch site and actively committed to the use of IPv6 within our network and to connect to our partners and peers.

What is IPv6 and why does Superloop promote it?

The Internet operates by transferring data in Internet Protocol packets. In order to send and receive these packets, each device connected to the Internet must have a unique address known as an IP Address.

Most devices on the internet have an IP version 4 address which has approximately four billion numbers available to allocate. With the massive expansion in the number of people, devices, web services and now the Internet of Things on the Internet means that IPv4 is running out of space.

IP version 6, the next-generation in addressing has been released to resolve this exhaustion of numbering available. With IPv6 there are more than 340 trillion, trillion, trillion addresses available to allocate and this will allow the connection of the billions of people and their devices to connect directly with one another.

At the same time as resolving this pressing issue, IPv6 has introduced a number of procedural and security fixes to how the protocol works making the process of communication over the Internet more even efficient. Superloop will continue to review industry and vendor releases and when considered stable, release IPv6 address preferences over IPv4 for address during name translation.

The majority of Operating Systems available on the market also automatically preference communication via IPv6 over the traditional IPv4 protocol when both devices (such as the client and server) are enabled for both protocols. As the Internet adopts IPv6 as the primary method of data communication IPv4 and CGNAT will become a method of compatibility with older devices being used for historic purposes only.
