Unclassified ARIN
Summary
Karib Cable
isp telecom media infrastructure
Four company names, three island carriers, and a netname used as its own registrant.
What it's used for
- A Caribbean cable operator. Forty IPv4 prefixes and one IPv6
/28announced from Saint Lucia, thirty-three thousand addresses, across two observed BGP neighbours.
Notable
- One long netname combining two company names, the word international and a three letter country code appears in the registrant field as well, so the same string identifies both the block and its owner.
- Several blocks are registered to a carrier from a different island, under a netname of three letters and a counter.
- Others carry an acquired company's name with the same country code, and one uses a carrier abbreviation followed by an address that ends in two zeroes where a prefix length would normally sit.
- The AS handle spells out the abbreviation for autonomous system, this AS number, and the country code.
- Eighteen addresses were queried for reverse DNS and none returned a name.
Interesting
- Caribbean telecoms consolidated heavily, and this record is the receipt. Four corporate names appear across blocks announced by one network, each surviving in whichever field nobody had to update.
- A netname repeated as the registrant means a data entry step copied one column into another. It is harmless and it makes the block look owned by a label rather than a company.
- Announcing space registered to a neighbouring island's carrier is normal here, where one operator serves several territories and the paperwork follows the island rather than the network.

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 1,773 prefixes, as published 2026-10-13. 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.
