Unclassified AFRINIC
Summary
Telkom SA Ltd. (SAIX)
isp transit legacy
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.zaDSL 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.xand165.xranges.
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.

Reputation
Classification and threat
Unclassified Not in the curated lists. Most of the ~80,000 allocated ASNs are not.
Spamhaus DROP
Not on ASN-DROP The network as a whole is not listed.
No DROP prefixes None of its announced space is on the DROP prefix list.
Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 436 networks and 1,771 prefixes, as published 2026-10-13. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.
FBI IC3
No IC3 indicators Nothing from the FBI IC3 feed.
IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
