Summary

MacroLan

South Africa · AI-generated

isp residential cable dsl

SEACOM-AS is operated by MacroLan, a regional cable and DSL provider in South Africa.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as dynamic.macrolan.co.za and router names like rtr3-c16-dc1.macrolan.co.za.
  • The AS announces 28,160 IPv4 addresses across 9 prefixes and 1 IPv6 prefix, while maintaining only 2 observed routing neighbours, a ratio indicative of an access network rather than a transit provider.

Notable

  • Registrants are primarily Seacom Western Cape (Pty) Ltd, with two /24 prefixes registered to MTN Business IP Maintainer, suggesting historical or leased address space.
  • The operator is identified in PeeringDB as MacroLan, a regional Cable/DSL/ISP, despite the registry handle referencing Seacom.
  • The inventory consists of a mix of /18, /20, /21, /22, and /24 blocks, all located in South Africa.

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 1,772 prefixes, as published 2026-10-15. 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.
