About this network

AS11325 is held by Altus Communications Inc., a Las Vegas, Nevada company that ARIN registered in 2012 and that markets itself as a private-label / wholesale telecom provider (transport, VoIP, ISP back-end services). The AS is small and single-homed in practice: RIS sees 6 IPv4 prefixes, 12,288 addresses, no IPv6, and just one observed neighbour — a stub, not a carrier.

What it's used for

The honest answer is that the space is mixed and mostly not Altus's own, so this AS should not be geolocated or typed with confidence. Only one announced prefix, 64.79.224.0/19, is registered to Altus itself (ARIN org handle AC-351). The remaining announced space is registered to Aventice LLC (a Boca Raton, Florida address-holding / hosting outfit) across 154.36.80.0/22, 154.37.64.0/22 and two 204.217.x/23s, plus a RIPE-managed 45.80.96.0/22 whose netname is literally hosting-clients under a maintainer handle. That is space from more than one registry, registered to a party unrelated to the holder, carrying a generic "clients" netname.

Notable

None of the twelve addresses sampled returned a PTR, so there is no first-party reverse DNS to corroborate the holder's own use of the space. Taken together — third-party registrants, cross-RIR blocks, a "hosting-clients" netname — this has the silhouette of leased address space announced under an ISP's AS number, which is exactly the pattern that defeats naive geolocation.

Interesting

We deliberately decline to give this AS a confident kind. Altus is a real, findable company, and a real carrier can legitimately announce a customer's or a lessor's space. But the inventory here is dominated by blocks whose registrant is somebody else, and calling it "residential" or "business" on the strength of the holder's marketing would be guessing. Treat any single-IP attribution inside 154.36/154.37, 45.80.96/22 or 204.217.20x as belonging to whoever currently leases it, not to Altus.
