Summary

// analyst note
Dormant Canadian DND (Canadian Forces Weather Services) ASN. RDAP/RIPEstat/CAIDA agree on zero current announcements and a self-only customer cone (rank 79,459). Upstreams, peer sample, community corroboration, and the bogon-overlap claim are Unknown/single-sourced.
// security note
NEUTRAL/DATED: no notable public abuse signal found as of 2026-08-01 (Spamhaus ASN-DROP, search-engine, NANOG-archive checks); ASN unrouted since 2018-07-16, so absence of abuse chatter partly reflects inactivity rather than confirmed clean history.

About this ASN.

Updated  ·  Confidence: Medium

AS825 is a long-dormant Canadian government ASN — registered to the Canadian Forces Weather Services (CFWS-NET), a Department of National Defence meteorological unit — that has announced zero IPv4 or IPv6 prefixes since mid-2018.

ARIN RDAP records the autnum's top-level registration date as 1994-05-04, and the network name CFWS-NET points to a military weather-forecasting operation rather than a commercial ISP. The registrant address traces to the CF Forecast Centre in Edmonton, Alberta.

Historically, AS825 originated exactly one prefix, 192.16.240.0/20 (roughly 4,096 addresses), visible from 2009-10-15 to 2018-07-16 per RIPEstat and bgp.he.net; it has not been seen in the global routing table since. One angle flags that this block overlaps an ARIN-maintained bogon range, which would make the historical announcement a legacy data-quality artifact rather than genuine production traffic — that read is single-sourced and tagged accordingly.

CAIDA's AS Rank places AS825 at 79,459 with a customer cone of exactly one ASN (itself) and zero prefixes or addresses, consistent with complete routing inactivity. No PeeringDB record exists for the ASN, and no upstreams, peers, or IX memberships could be confirmed from any source. RPKI validation does not apply because there are no current announcements to check against ROAs.

ARIN's registration status for AS825 is still Active, but the listed administrative/technical contact has reportedly gone unresponsive to ARIN validation attempts since 2010, suggesting the record is stale even though it has not been revoked or reclaimed.

Security/abuse context (NEUTRAL, DATED)

no notable public abuse signal found as of 2026-08-01 in Spamhaus ASN-DROP or search-engine/NANOG-archive checks; the ASN has been unrouted since 2018, so absence of abuse chatter is partly explained by inactivity rather than a confirmed clean operational history

Network & routing

Network type
government/military meteorological network; legacy/inactive, not a commercial transit or eyeball ISP [Likely] — https://rdap.arin.net/registry/autnum/825
Size
dormant — 0 IPv4/IPv6 prefixes currently announced; historically 1 IPv4 prefix, 192.16.240.0/20 (~4,096 addresses), seen 2009-10-15 to 2018-07-16; customer cone = 1 ASN (itself), 0 prefixes, 0 addresses
[Confirmed] — https://stat.ripe.net/AS825, https://asrank.caida.org/asns/825, https://bgp.he.net/AS825
Routing/peering
not announced since 2018-07-16; not a CAIDA clique member and not seen in the topology graph; no PeeringDB record (peeringdb.com/asn/825 returns 404); no upstreams confirmed; one historical IPv4 peer, AS3766 (Shared Services Canada), reported by a single angle [Likely for the AS3766 peer, Confirmed for no-current-peers] — https://bgp.he.net/AS825, https://www.peeringdb.com/asn/825
RPKI
not assessable — AS825 announces no current prefixes, so there is nothing to validate against ROAs [Confirmed] — https://stat.ripe.net/AS825
Notable usage
single historical /20 announcement between 2009 and 2018; possible overlap with an ARIN-maintained bogon range flagged by one source only, not corroborated elsewhere [Likely] — https://bgp.he.net/AS825
Related ASNs
none confirmed as commonly operated with AS825; AS3766 (Shared Services Canada) appears only as a historical routing peer, not a sibling ASN [Unknown] — https://bgp.he.net/AS825
Analyst note
Encountered as a dormant Canadian Department of National Defence ASN (Canadian Forces Weather Services). RDAP, RIPEstat, and CAIDA agree on zero current announcements and a self-only customer cone. Community corroboration (NANOG, Reddit) is absent; upstreams, peers, and the bogon-overlap claim remain single-sourced and should be revisited if the ASN is re-researched.
