Summary

Internet Solutions (NTT / Dimension Data)

South Africa · AI-generated

isp backbone

Internet Solutions (IS) — a long-established South African business ISP and transit provider, part of the Dimension Data / NTT group.

What it's used for

  • Enterprise internet access, connectivity, and transit across South Africa and the region.

Notable

  • Not a mobile carrier: this is a business-focused ISP and backbone network, so addresses here are corporate connections and hosted services rather than consumer mobile devices.
  • One of the older and larger commercial networks in South Africa, now folded into the NTT DATA global organisation.

Interesting

  • Internet Solutions was among the pioneers of commercial internet in South Africa before being absorbed into Dimension Data and later NTT.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
