AS16580 ATHABASCA-U - Athabasca University
Unclassified ARIN
Summary
Athabasca University
education research infrastructure
Fifteen prefixes, one netname, one parent range, and not a single address that answers.
What it's used for
- A university's network. Fifteen IPv4 prefixes announced from Canada, no IPv6, seven thousand four hundred and twenty-four addresses, through two observed BGP neighbours.
Notable
- Every listed block carries the same netname, which is also the AS handle: the university's name and a single letter for the word university.
- Every block sits inside one parent range, cut into pieces of three different sizes and announced separately rather than as the whole.
- The registrant is the university on all of them, written out in full with no abbreviation.
- Eighteen addresses were queried for reverse DNS and none returned a name.
- Two observed neighbours carry all fifteen prefixes.
Interesting
- Splitting one range into fifteen announcements and giving them all one name means the fragmentation is operational, not administrative. Somebody is steering pieces of the campus separately, and the registry was never told.
- Every extra piece is a routing table entry carried by every router on the internet. Fifteen entries where one would do is a small cost paid by everyone else, which is why the practice is discouraged and why it remains common.
- A university with two upstreams and no reverse names at all is unusual. Campuses normally name their machines; this one publishes nothing outward, and the addresses arrive anonymous.

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 2026-10-31, 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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
