Summary

Canada · AI-generated

business fibre canada

The AS handle CDSI is held by Beanfield Technologies Inc.

What it's used for

  • The address space carries corporate and fibre infrastructure, evidenced by registrant netnames CDSI, BNFD, and APTUM, and reverse DNS entries pointing to beanfield.net and smtp.ariad.ca.
  • The AS announces 37,632 IPv4 addresses across 43 prefixes with only 4 observed neighbours, a ratio that indicates an internal corporate estate or access network rather than a transit provider.

Notable

  • All registrants in the RDAP sample are Beanfield Technologies Inc., which aligns with the AS holder.
  • The address inventory is finely subdivided into numerous /21, /22, and /23 blocks, consistent with site-by-site segmentation for a fibre operator.
  • Secondary sources identify the operator as Aptum Fibre, a Toronto-based NSP, confirming the business identity behind the CDSI handle.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
