About this network

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-AFRINIC for 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.
