AS612

Not announced

Operated by AIRFIBER521 - AirFiber, Inc..

Summary

// analyst note
Dormant, RIR-active but unrouted small-WISP ASN. allocated_date read from the RDAP autnum object's TOP-LEVEL events[] (registration: 2017-08-04T13:34:39-04:00), explicitly avoiding nested entity-record dates (HANSO29-ARIN 2012-08-30, AIRFI-1 org 2012-10-26) which are decoys, not the ASN's own allocation event.
// security note
No confirmed public abuse signal as of 2026-07-16 (Spamhaus ASN-DROP, NANOG archives, AbuseIPDB checked).

About this ASN.

Updated  ·  Confidence: Medium

AS612 is an ARIN-registered autonomous system number held by AirFiber, Inc., a small, locally-owned fixed-wireless Internet service provider (WISP) headquartered at 521 Tower Ave, Superior, Wisconsin. The ASN's top-level ARIN RDAP autnum record carries a registration event of 2017-08-04, distinct from — and not to be confused with — the nested registrant/contact entity records (org AIRFI-1 registered 2012-10-26; admin/tech/abuse POC HANSO29-ARIN, Shawn Hanson, registered 2012-08-30), which are entity-level dates rather than the ASN's own allocation event. Operationally, AS612 is currently dormant: it announces zero IPv4 and zero IPv6 prefixes, has zero visible BGP peers or upstreams in RIPEstat's RIS data, and has not been observed in the global routing table since 2015-11-11, when it last originated 168.151.30.0/24. Historically it originated at least 19 IPv4 prefixes going back to 2002 (first seen: 207.35.226.0/24). CAIDA ranks it 79,459 with a customer cone of exactly itself. No PeeringDB network record exists, and no confirmed public abuse signal was found, though one research pass surfaced a possibly mismatched Spamhaus listing under an unrelated organization name that conflicts with the RDAP-confirmed registrant and should not be treated as fact.

Security / abuse context (dated 2026-07-16)

no confirmed public abuse signal — checked against Spamhaus ASN-DROP, NANOG mailing-list archives, and AbuseIPDB, with no AS612-specific record found [Likely]. One research pass reported an ASN-DROP listing under a different organization name ("PRECISION TECHNOLOGY Inc.") that conflicts with the RDAP-confirmed registrant (AirFiber, Inc.) — treated as an unverified/likely-mismatched entity, not recorded as fact

Network & routing

Network type
small regional fixed-wireless ISP (WISP) serving Duluth MN, Superior WI, and Hermantown MN [Likely] — operator's own site (myairfiber.com) could not be fetched this session (TLS handshake failure, reproduced both via WebFetch and shell curl -I); corroborated only via third-party listings (ispreports.org, broadbandnow.com, Superior WI Chamber of Commerce)
Size / routing status
NOT currently announced — 0 IPv4 / 0 IPv6 prefixes; not visible in the DFZ since 2015-11-11; historically originated ~19 IPv4 prefixes including 207.35.226.0/24 (first seen 2002-08-10) and 168.151.30.0/24 (last seen 2015-11-11) [Confirmed] — https://stat.ripe.net/AS612, https://bgp.he.net/AS612
Routing / peering
0 RIS peers seeing it (0/327 v4, 0/322 v6); CAIDA degree total 0 (customer 0, peer 0, provider 0); no PeeringDB network record exists for AS612 (404 from both web UI and API) [Confirmed]. Historical upstream/peer relationships per bgp.he.net: GTT Communications (AS3257), GTT Americas LLC (AS4436), and Arelion/Telia Sweden AB (AS1299)
[Likely] — https://www.peeringdb.com/asn/612, https://bgp.he.net/AS612
RPKI
not assessable — AS612 currently announces no prefixes, so RIPEstat's rpki-validation query was explicitly skipped (requires a prefix) and no ROAs exist to check [Confirmed] — https://stat.ripe.net/AS612
Notable usage
none found — no news coverage, incident write-ups, or major-network affiliations; reads as a small, locally-owned regional WISP with no distinguishing notable usage [Unknown]
Related ASNs
none identified in this pass
Analyst note
dormant, unrouted small-WISP ASN, RIR-administratively active but with no live routing footprint since 2015; operator's own website was unreachable this session due to a reproducible TLS fault, so operator-official claims (network_type, peering) are corroborated only via secondary sources and tagged accordingly.
