Summary
University of Waterloo
education university research legacy
The campus network of the University of Waterloo in Ontario.
What it's used for
- Campus networking for teaching and research. The sampled reverse DNS answers under
nsx.uwaterloo.cawith per-building names, the shape of a campus addressing plan organised by physical location rather than by service.
Notable
- Almost the entire announcement is a single legacy
129.97.0.0/16registered asUWATERLOO-V4. Two IPv4 prefixes and three observed BGP neighbours make this about as simple as a large network gets: one class B, a couple of upstreams, no fragmentation. - One
/24is registered to an independent computer consultant rather than to the university, so a small piece of unrelated space rides along inside the campus announcement.
Interesting
- Waterloo is the Canadian university most closely tied to the country's tech industry, and it was on the internet early enough to hold a class B outright. Canadian institutions drew from the same early allocation pool as their US counterparts, which is why a single campus here holds 65,000 addresses while a comparable university founded a decade later would be renting them.

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 2026-10-18, 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: 442 networks and 1,784 prefixes, as published 2026-10-19. 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.
