Saint Vincent and the Grenadines · AI-generated

telecom residential caribbean isp

COLUMBUS-COMMUNICATION-SVG is operated by Columbus Communication St. Vincent and the Grenadines Ltd., a telecommunications provider in the Eastern Caribbean.

What it's used for

  • The address space carries a mix of netnames including COLUMBUS-COMMUNICATION-SVG, COLUMBUS-SVG-LIMITED, and legacy BDS-NET and CABLE-AND-WIRELESS blocks, indicating a consolidated regional ISP estate.
  • With 21,504 IPv4 addresses across 36 prefixes and only 2 observed neighbours, the high address-to-neighbour ratio identifies this as an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of residential and business subscriber traffic for Saint Vincent and the Grenadines, supporting the local telecommunications market.

Notable

  • Registrants for the largest prefixes include both Columbus Communication St. Vincent and the Grenadines Ltd. and Cable & Wireless (Barbados) Limited, reflecting historical consolidation of Caribbean telecom assets.
  • The inventory includes prefixes originally registered to Cable & Wireless entities, such as BDS-NET8 and CWJ-NET-BLOCK, which are now announced under the Columbus AS.
  • The address inventory is fragmented into 36 distinct IPv4 prefixes, ranging from /21s to /24s, with no IPv6 prefixes currently announced.

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.
