Summary

education business canada
AS-COTNA is operated by College of the North Atlantic.
What it's used for
- The address space carries institutional traffic for the College of the North Atlantic, a post-secondary educational institution in Atlantic Canada.
- The AS announces 1280 IPv4 addresses across 2 prefixes with 2 observed neighbours, indicating a small, self-contained network typical of a single-site or limited-campus educational facility.
- Traffic consists of student, faculty, and administrative web, email, and research endpoints associated with the college's campuses.
Notable
- The RDAP registrants for both announced prefixes are listed as Eastlink HSI, while the AS holder is the College of the North Atlantic, suggesting the institution leases or sources its IP space from Eastlink.
- The address inventory is compact, consisting of one /22 and one /24 block, both located in Canada.

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.

Reputation
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.
