Summary
Datacom Caribe (Coqui.net)
COQUI-NET is Datacom Caribe, Inc. of San Juan, the internet arm long associated with the Puerto Rico Telephone Company. It is one of the island's principal consumer broadband networks.
What it's used for
RIS observes 134 IPv4 prefixes carrying 274,432 addresses plus 18 IPv6 prefixes, including a 2606:5f00:8000::/33. The v4 side is anchored by genuinely large blocks: 66.50.0.0/16, three /17s (64.237.128.0/17, 173.215.128.0/17, 72.50.0.0/17) and a row of /18s. A quarter of a million addresses in one territory is an ISP serving a mass market, not an enterprise.
The reverse DNS confirms it and identifies the subscriber technology directly. Sampled names are adsl-64-237-128-5.prtc.net, adsl-72-50-0-5.prtc.net, cvx-ppp-66-50-50-5.coqui.net and static-173-215-128-5.prtc.net. adsl- is DSL subscriber space; cvx-ppp- names a Cisco/Redback-style PPP aggregation shelf terminating dial or DSL sessions. These are home and small-business lines.
Notable
The kind is residential eyeball, and the pool naming settles it against any hosting reading. Note that prtc.net rDNS on coqui.net-held space is exactly the case where rDNS shows what the space carries under a sister brand, not a different holder.
Thirty observed BGP neighbours is consistent with a well-connected island ISP that peers at regional exchanges. It is far too few for a wholesale transit carrier of this address size.

Interconnection
Peering at a glance
Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
