Summary

BCWARN

Canada · AI-generated

amateur radio data network

The AS handle BCWARN is held by British Columbia Frequency Modulation Communications Association.

What it's used for

  • The address space carries amateur radio data traffic, evidenced by netnames AMPRNET and UBC-BC-WARN associated with registrants Amateur Radio Digital Communications and British Columbia Frequency Modulation Communications Association.
  • The AS announces 5120 IPv4 addresses across 3 prefixes with only 1 observed neighbour, indicating a small, self-contained network rather than a transit or large access provider.
  • Traffic consists of high-speed data communications for amateur radio groups, designed to operate independently of commercial internet providers.

Notable

  • Registrants align with the announcer, with Amateur Radio Digital Communications holding the AMPRNET space and the association holding the UBC-BC-WARN space.
  • The inventory consists of three distinct IPv4 blocks: 44.32.40.0/21, 44.135.208.0/21, and 206.12.104.0/22.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-11, 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: 453 networks and 1,846 prefixes, as published 2026-11-11. 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.
