CALCULQUEBEC is the autonomous system for Calcul Quebec, the national high-performance computing centre for Quebec.

What it's used for

  • The address space carries high-performance computing and research infrastructure, evidenced by reverse DNS entries like 198-168-187-255.cloud.computecanada.ca and 198-168-189-254.vm.juno.calculquebec.ca.
  • The AS announces 2560 IPv4 addresses and 1 IPv6 prefix, with only 1 observed neighbour, indicating a dedicated research network rather than a transit provider.

Notable

  • Registrants include both McGill University (for MCGILL-C) and Calcul Quebec (for MCGILL-CALCULQUEBEC and ETS-CALCULQUEBEC), reflecting the collaborative nature of Quebec's academic computing infrastructure.
  • The inventory consists of three IPv4 prefixes, including a /21 block and two /24 blocks, all located in Canada.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-11, 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: 432 networks and 1,768 prefixes, as published 2026-10-12. 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.
