Summary
Cogeco Connexion Inc.
isp legacy
CC-3272 is Cogeco Connexion, the cable broadband and telephony arm of Cogeco, serving Quebec and Ontario. RIS sees a large eyeball network: 83 IPv4 prefixes, 417,280 addresses, 4 IPv6 /32s, and 19 observed neighbours.
What it's used for
Residential and small-business internet access. The reverse DNS says so directly and repeatedly. Sampled addresses across seven different announced blocks come back as <a>-<b>-<c>-<d>.resi.cgocable.ca — resi is not subtle — while another cluster returns .mc.derytele.com, the naming of DERYtelecom, the Quebec cable operator Cogeco acquired and now runs inside the same AS. Both patterns are per-address templated subscriber naming, which is what a cable modem pool looks like and is nothing like server rDNS.
Notable
Nineteen observed neighbours against 417,000 addresses is the profile that distinguishes an eyeball ISP from a carrier. A wholesale transit provider with this much address space would peer with hundreds or thousands of ASes; Cogeco instead terminates a modest set of upstreams and exchange sessions and pushes the traffic down to subscribers. Almost every prefix sampled is registered to CC-3272 (org: Cogeco Connexion inc) itself. The one exception, 205.236.42.0/24 registered to Sogi Informatique Ltée, is a named Quebec business, not an anonymous shell — a customer or acquired-company block announced by its provider, and exactly the false positive not to mistake for leased address space.
Interesting
57.134.0.0/17 is the standout prefix. The 57.0.0.0/8 block is a legacy allocation with no connection to Canadian cable, and its presence here is a clean demonstration that a legacy /8 tells you nothing about geography — inter-RIR and inter-company address transfers have long since scrambled any such shortcut. The block now carries resi.cgocable.ca subscribers in Canada, and the reverse DNS, not the /8, is what tells you that.

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: 436 networks and 1,771 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.
