AS37100 SEACOM-AS
Unclassified APNIC
Summary
SEACOM
transit submarine pan-african isp
The AS handle SEACOM-AS is held by SEACOM Limited.
What it's used for
- The address space carries SEACOM's submarine cable infrastructure and associated services, with netnames consistently identified as
ORG-SL75-AFRINICfor the majority of prefixes. - With 1,072,896 IPv4 addresses announced across 17 prefixes and 1,818 observed neighbours, the high neighbour count relative to the address inventory indicates a transit and peering role rather than a pure access network.
Notable
- Registrants for the largest prefixes, including 105.16.0.0/13 and 105.24.0.0/14, are uniformly listed as SEACOM Limited, aligning with the announcer.
- SEACOM is known for developing Africa's first broadband submarine cable system along the eastern and southern coastlines, providing pan-African connectivity.
- The inventory includes a prefix 154.72.240.0/20 registered to Pamoja, Ltd, which differs from the primary SEACOM registrant, suggesting leased space or a distinct operational segment.

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 1,783 prefixes, as published 2026-10-17. 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.
