Summary
Algoma University
education research business
Two adjacent blocks announced separately rather than as one.
What it's used for
- A university network. Two IPv4 prefixes announced from Canada, no IPv6, and three observed BGP neighbours.
Notable
- The two prefixes are adjacent, a
/24sitting immediately below a/23in the same range, and they are announced as two routes rather than combined. - Both carry the same netname and the same registrant, so nothing in the registry separates them.
- The AS handle appends a three-letter site code to the university's short name, a code that appears in no other field.
- Six addresses were queried for reverse DNS and none returned a name.
- The routing history begins in 2007, much later than the AS number would suggest.
Interesting
- Announcing two adjacent blocks separately rather than as one covering prefix is a small choice with a real cost: two entries in every routing table that carries them, forever, to describe contiguous space. It usually means the blocks were assigned at different times and nobody revisited the configuration.
- A late first-seen date on a low AS number means the number sat unused, or was used where no collector watched, before this network started announcing. The number implies an age the routing does not support.
- Seven hundred addresses and three upstreams for a whole university is a small footprint, which fits an institution whose research network reaches it through one of those upstreams rather than directly.

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 2026-10-18, 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.
