AS7289 AS-QT
Unclassified ARIN
Summary
QuantaRa Tech LLC
legacy
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 unrelated2a0c::,2a0e::,2a0f::,2a11::and2a12::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.

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 1,773 prefixes, as published 2026-10-13. 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.
