Summary

Canada · AI-generated

education university research bilingual

UOTTAWA is the autonomous system for the University of Ottawa.

What it's used for

  • The address space carries university infrastructure, with netnames UOTTAWA, UOTTAWA-HEALTH, and WALL-UOTTAWA indicating general campus, health sciences, and specific facility segments.
  • The AS announces 69,896 IPv4 addresses across 4 prefixes, with only 2 observed neighbours, a ratio characteristic of an internal institutional network rather than a transit provider.

Notable

  • Registrants for the three largest prefixes are all listed as University of Ottawa, while the smallest prefix 66.97.23.248/29 is registered to ORION; Engineering under the netname ORION.
  • The inventory consists of one /16, one /20, one /24, and one /29, reflecting a finely subdivided corporate estate typical of a large university campus.

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.
