Summary
Air Wisconsin Airlines
enterprise legacy
AWAC-HQ is Air Wisconsin Airlines, a US regional carrier that has long flown feeder services on behalf of larger airlines. The handle says what the network is: the airline's headquarters, not its fleet.
What it's used for
Corporate systems at a single site. RIS sees two adjacent /24s, 67.52.28.0/24 and 67.52.29.0/24 (512 addresses), through two observed neighbours. Both are registered to AIR WISCONSIN AIRLINES LLC itself, so the inventory matches the holder exactly. Two contiguous blocks, two upstreams and a -HQ handle describe an enterprise edge — office and back-office connectivity, multihomed for availability — with no access pool, no hosting tenants and no wholesale role.
Notable
Every sampled address answers under biz.spectrum.com — Charter's generated naming for business subscribers, distinct from the res.spectrum.com pattern used for residential cable. That is the airline's ISP putting default rDNS on a customer block, and it is worth being precise about what it proves: rDNS shows what the space carries and which carrier serves it, never who holds it. Here the registry says Air Wisconsin and the PTRs say Spectrum, and both are correct — a company on its provider's default reverse zone.
Interesting
An airline's public address footprint is far smaller than its operation. Booking, check-in and flight-ops platforms are overwhelmingly carrier- or vendor-hosted, so a regional airline's own AS shows only the headquarters edge — two /24s standing in for an entire company.

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-15, 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: 442 networks and 1,781 prefixes, as published 2026-10-16. 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.
