Summary

Australia Post

Australia · AI-generated

business logistics corporate internal

The AS handle AUSPOST is held by Australia Post.

What it's used for

  • The address space is registered under the netname AUST-POST with the registrant Australian Postal Corporation, indicating an internal corporate estate for the national postal service.
  • The AS announces 63232 IPv4 addresses across 31 prefixes, all located in Australia, while maintaining only 2 observed neighbours. This high address-to-neighbour ratio, combined with the single corporate registrant, identifies this as a segmented internal network rather than a transit or access provider.

Notable

  • All sampled prefixes share the same registrant, Australian Postal Corporation, which aligns directly with the AS holder name.
  • The inventory consists entirely of IPv4 space within the 155.144.0.0/16 range, subdivided into various /19, /20, /21, /22, and /23 blocks, reflecting site-by-site or functional segmentation of the corporate infrastructure.

Internet exchanges

No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-14, 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 1,772 prefixes, as published 2026-10-15. 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.
