Summary
University of Guelph
education university research canada
UOGUELPH is the autonomous system for the University of Guelph.
What it's used for
- The address space carries university infrastructure, with all registrants identified as "University of Guelph; Network Operations Centre" and netnames set to
UOGUELPH. - The AS announces 65,536 IPv4 addresses across 6 prefixes, all within the 131.104.0.0/17 block, while maintaining only 2 observed routing neighbours. This high address-to-neighbour ratio indicates an access or eyeball network serving the campus community rather than a transit provider.
Notable
- All six announced prefixes share the same registrant, "University of Guelph; Network Operations Centre," and the netname
UOGUELPH, confirming a unified internal estate. - The address inventory is finely subdivided into six distinct prefixes ranging from /17 to /21, reflecting site-by-site segmentation typical of a large institutional network.

Interconnection
Peering at a glance
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 2026-10-19, 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 1,783 prefixes, as published 2026-10-20. 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.
