Summary
Dalhousie University
education university research legacy
DALUNIV is the Autonomous System of Dalhousie University, a research university in Halifax, Nova Scotia, and the largest in Atlantic Canada.
What it's used for
- Campus networking across Dalhousie's Halifax and Truro sites: teaching, research, administration, libraries, residences and the university's own hosted services.
- The rDNS inside
129.173.0.0/16is unambiguously institutional — names likegw81ad0020.backbone.dal.ca, campus VPN concentrators and lab/application hosts ondal.casubdomains. No subscriber pools.
Notable
- This is an institutional network. An address here is a university-managed host or a client on the campus network, not a consumer line and not a commercial server.
- It carries two legacy
/16s (129.173.0.0/16and134.190.0.0/16, the latter from the former Technical University of Nova Scotia, which merged into Dalhousie) plus a140.230.0.0/16and some192.75.x/24s — roughly 197k addresses, and a2001:410::IPv6 allocation from CANARIE's space.
Interesting
- Canadian universities reach the internet through CANARIE and their provincial regional network, so a campus AS of this size shows only a handful of BGP neighbours: the research network carries most of the traffic and commercial transit is a backstop.

Classification and threat
Education University, school or national research and education network.
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 1,781 prefixes, as published 2026-10-16. 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.
