ORG-EHSL1-AFRINICfor Eskom Holdings SOC Ltd, indicating an internal corporate estate for South Africa's primary electricity utility. - The AS announces 65,536 IPv4 addresses across 50 prefixes, all located in South Africa. With only 4 observed neighbours, the ratio of address space to peering partners suggests a large internal network rather than a transit or access provider.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
