Summary
CW-E (Connecting Windsor-Essex)
education university government research legacy
CA-CW-E is Connecting Windsor-Essex, a not-for-profit public-sector fibre network in Windsor, Ontario (500 Ouellette Avenue). It is a shared regional network: the AS announces space belonging to its member institutions rather than to CW-E as a commercial provider.
What it's used for
- Aggregating internet and inter-site connectivity for the public institutions of the Windsor-Essex region. RIS sees 13 IPv4 prefixes / 71,424 addresses and 4 observed neighbours — a small number of upstreams feeding a large block of institutional space, which is the shape of a community aggregator, not a carrier.
Notable
- The registrant list is the membership roll, and it is what makes this network classifiable at all:
137.207.0.0/16belongs to the University of Windsor;205.211.88.0/23and205.211.90.0/24to St Clair College of Applied Arts and Technology;205.207.192.0/21,205.207.200.0/22and205.207.190.0/23to the Essex County Library;199.71.141.0/24to the Greater Essex County District School Board;209.202.75.0/24to WEDnet. Different registrants, all education or local government, all in one region. - That pattern superficially resembles the multiple-unrelated-registrant tell for leased address space, and it is worth saying plainly why it is not: the registrants are large, findable public institutions with their own campuses and their own rDNS (
ip0-5.rf.uwindsor.ca), and they are a coherent regional consortium rather than a set of shells. A member-owned aggregator legitimately announces its members' PI space. - The
/16alone accounts for most of the address count; the University of Windsor is by far the largest member.
Interesting
- No IPv6 is announced by the aggregate AS.

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 2026-10-10, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
