Summary

Airservices Australia

Australia · AI-generated

government aviation infrastructure business

The AS handle AIRSERVICESAUS-AP is held by Airservices Australia, the government agency responsible for air traffic control and aviation services in Australia.

What it's used for

  • The address space is registered under the netname AIRSERVICES-NON-AU with registrant IRT-AIRSERVICES-NON-AU, indicating internal corporate infrastructure rather than public consumer access.
  • The AS announces 65536 IPv4 addresses across 10 prefixes, all within the 168.132.0.0/16 range, with only 1 observed neighbour, suggesting a self-contained internal network estate.

Notable

  • All registrants in the RDAP data consistently identify Airservices Australia, matching the AS holder.
  • The address inventory is finely subdivided into 10 prefixes of varying sizes, consistent with site-by-site segmentation for an internal corporate or government estate.

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.
