AS5713 — SAIX-NET

AS5713 announces 157 IPv4 prefixes covering 1,492,736 addresses and 14 IPv6 prefixes.

About this network

Telkom SA's Internet backbone, historically branded SAIX, under the handle SAIX-NET. It is one of the oldest and largest networks in Southern Africa.

What it's used for

• Carries Telkom's own consumer Internet subscribers: reverse DNS across the space resolves to telkomadsl.co.za DSL customer names.
• Acts as upstream transit for other South African networks, including Telkom's own sibling ASNs, and peers very widely.
• Originates several hundred prefixes drawn mostly from the 197.x and 165.x ranges.

Notable

• SAIX stands for "South African Internet Exchange", but despite the name it was never an exchange point: it was and is a transit ISP run by Telkom. The inventory (eyeball DSL customers plus downstream transit) is the honest description, not the branding.
• Telkom operates a family of ASNs; this one is the Internet-facing backbone. See AS5734 for the sibling network carrying Telkom's hosting and network-management address space.
