Summary

Ausra

United States of America · AI-generated

solar energy business us

AUSRA-SYSTEMS is operated by Ausra LLC.

What it's used for

  • The address space carries corporate infrastructure for a concentrated solar power provider, evidenced by the netname AUSRA-EU and the registrant Ausra LLC.
  • The AS announces 256 IPv4 addresses and 3 IPv6 prefixes, with only 1 observed neighbour, indicating a small, isolated corporate network rather than a transit or access provider.

Notable

  • The registrant Ausra LLC matches the AS holder, confirming consistent ownership of the announced space.
  • Ausra was acquired by AREVA, a French nuclear and energy group, which launched a new business unit for concentrated solar power solutions following the acquisition.
  • The inventory consists of a single /24 IPv4 block and three IPv6 prefixes, reflecting a compact internal estate for a specialized industrial operator.

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.
