Summary
Seneca College of Applied Arts and Technology
SENECA-ASN-01 is Seneca College of Applied Arts and Technology — now branded Seneca Polytechnic — a large public post-secondary institution in the Greater Toronto Area with campuses across Toronto, North York, Markham and Newmarket. AS10265 is the campus network.
What it's used for
Everything a campus does with IP: student and staff wireless, lab and classroom machines, residence networks, administrative systems, and the college's public-facing web and mail. The AS announces 3 IPv4 prefixes totalling 16,384 addresses and no IPv6 — a 142.204.0.0/18 plus its own two constituent /19s, 142.204.0.0/19 and 142.204.32.0/19. Announcing a /18 alongside the two halves that make it up is ordinary campus traffic engineering: the covering route keeps reachability if one path fails, while the /19s let each half be steered toward a different upstream.
Notable
This is an education network, and the routing corroborates the name rather than merely repeating it. Two observed BGP neighbours against 16,384 addresses is exactly the shape of a Canadian institution connected to a provincial research-and-education network with a commodity-internet backup: enough for redundancy, far too few for any wholesale role. The address count is likewise right for a campus of Seneca's size — tens of thousands of addresses, none of them subscriber pools.
Nothing here is hosting or transit. Geolocate the space to the Toronto area, and expect students, staff and campus infrastructure behind any address in it.

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 2026-10-16, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-17. 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.
