Summary

Telkom SA

South Africa · AI-generated

residential dsl access south-africa

The AS handle CYBERNEST is held by Telkom SA Ltd.

What it's used for

  • The address space carries residential DSL access, evidenced by reverse DNS entries such as dsl-148-156-128.telkomadsl.co.za and dsl-148-128-64.telkomadsl.co.za.
  • The network announces 768 IPv4 addresses across 2 prefixes with only 1 observed neighbour, a ratio characteristic of an access or eyeball network rather than a transit provider.

Notable

  • RDAP registrants for both announced prefixes are listed as unknown, which does not contradict the registry holder identity of Telkom SA Ltd.
  • The address inventory consists of two IPv4 blocks: 41.148.156.0/23 and 41.148.128.0/24, with no IPv6 prefixes in inventory.

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
