AS11964 AWAC-HQ

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.
