Summary
The Michener Institute of Education at UHN
education legacy
THE-MICHENER-INSTITUTE-OF-EDUCATION-AT-UHN belongs to the Michener Institute, a Toronto post-secondary school for applied health sciences that trains diagnostic and therapeutic health technologists. It is part of University Health Network, the Toronto hospital and research group, which is what the -AT-UHN in the handle records.
What it's used for
A campus network, and a small one. RIS sees a single announced prefix, 108.174.128.0/23 (512 addresses), and two observed BGP neighbours. That shape is an institution buying transit from a couple of upstreams for its own site, not a network that resells connectivity: a carrier of any size peers with hundreds of ASes, and two neighbours is what a single-campus operator looks like.
The prefix registrant confirms the holder rather than complicating it. ARIN registers 108.174.128.0/23 as MICHNET to The Michener Institute for Applied Health Sciences, the school's own legal name. Registrant and announcer are the same organisation, so nothing here suggests the number or the space is being flown on someone else's behalf.
Notable
The registered org name is the older one, from before the school was folded into UHN and rebranded; the AS handle carries the newer name. That mismatch is ordinary registry lag, not a change of control.
Two addresses were sampled for reverse DNS and neither answered. That is a sample of two out of 512 and supports no conclusion in either direction.

Interconnection

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 2026-10-15, 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 1,781 prefixes, as published 2026-10-16. 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.
