submarine fiber caribbean transit

ASN-SCF-45 is held by Southern Caribbean Fiber.

What it's used for

  • The address space carries a mix of Cogent Communications, LLC (COGENT-A), Southern Caribbean Fiber (SCF-AS63351-SOUTHERN-CARIBBEAN-FIBER), and Global Caribbean Network (GLOBAL-CARIBBEAN-NETWORK) netnames.
  • The AS announces 2560 IPv4 addresses across 5 prefixes and 1 IPv6 prefix, with 10 observed neighbours, indicating a transit or interconnection role for the submarine cable infrastructure.
  • Traffic from this AS consists of backbone and inter-island connectivity for the Southern Caribbean Fiber submarine cable system, which links 15 islands in the Eastern Caribbean.

Notable

  • Registrants include Cogent Communications, LLC, Southern Caribbean Fiber, and Global Caribbean Network, reflecting the multi-stakeholder nature of the submarine cable consortium.
  • Southern Caribbean Fiber was formerly known as Antilles Crossing and has been rebranded as part of Digicel's Deep Blue One cable system.
  • The inventory includes a large /22 block from Cogent and smaller blocks from other registrants, typical of leased or shared submarine cable address space.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
