AS7289 AS-QT

AS-QT is registered to QuantaRa Tech LLC, a US company with an ARIN

registration address in Aurora, Colorado. The ASN record was (re)created in

January 2025, so this is a modern holder of a low AS number, not an

early-internet network.

What it's used for

• Announces a small, mixed set of prefixes: two ARIN /24s and two /24s from an Austrian research allocation, alongside about a dozen RIPE IPv6 /29s drawn from unrelated 2a0c::, 2a0e::, 2a0f::, 2a11:: and 2a12:: blocks.
• None of the announced ranges carry reverse DNS that identifies a service, so the actual workload on this network cannot be confirmed from the outside.

Notable

• The shape is unusual and worth flagging: the IPv4 it originates is registered to other organisations, and the IPv6 is a scattered collection of RIPE allocations from many different /12s. That is the profile of address brokering or IP leasing rather than of a network serving its own users.
• Because the operator's own description and its announced inventory don't line up, this AS is deliberately left unclassified rather than being labelled as hosting or as an ISP.

Interesting

• AS7289 sits in a block ARIN handed out in 1996, but the current registration dates from 2025 — a reminder that a low AS number does not by itself imply an early-internet pedigree.
