Summary

McGill University

Canada · AI-generated

education research infrastructure

A university announcing two hospitals, a research network, and a netname that labels the wrong octets.

What it's used for

  • A university network carrying affiliated teaching hospitals. Ten IPv4 prefixes and one IPv6 /48 announced from Canada, one hundred and forty-eight thousand addresses, through one observed neighbour.

Notable

  • Two of the blocks are /16 allocations, from an era when universities were given space on that scale.
  • Two hospitals hold their own registrations inside this routing, each with a netname naming the institution, the province and the country.
  • One block is registered to the provincial research network under a netname citing octets that do not match the block it labels.
  • One /24 is named for guest access and the roaming federation used between institutions, so the registry states which range carries visitors.
  • Three of eighteen sampled addresses answered, each naming a hospital site and a research institute before the university's domain.

Interesting

  • Naming the guest range in the registry is honest and useful, and it also tells anyone scanning which addresses belong to devices the institution does not control.
  • The hospital reverse names identify the building from the address alone, which is exactly what an operator wants during an incident and rather more than a stranger needs.
  • A netname pointing at the wrong octets is harmless until someone automates from it, at which point the block is attributed to a range it has nothing to do with.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-10, 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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
