Unclassified ARIN
Summary
Durham College
education campus canada oshawa
DC-UOIT-NET is the autonomous system for Durham College, a public post-secondary institution in Ontario.
What it's used for
- The address space carries campus network infrastructure, evidenced by reverse DNS names such as
net715.dc-uoit.net,nat-admin.res.dc-uoit.net, andnet09.svil.netcampus.ca. - The AS announces 5376 IPv4 addresses across 6 prefixes with only 1 observed neighbour, a ratio characteristic of a single-site or multi-campus educational network rather than a transit provider.
Notable
- All registrants for the announced prefixes are listed as "DURHAM COLLEGE OF APPLIED ARTS AND TECHNOLOGY; DC-UOIT Admin Team," which aligns perfectly with the AS holder.
- The address inventory consists of five /22 blocks and one /24 block, all located in Canada, reflecting a consolidated internal estate for the college's Oshawa and Whitby campuses.

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: 453 networks and 1,853 prefixes, as published 2026-11-05. 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.
