Summary

APNIC Research and Development

Australia · AI-generated

research infrastructure apnic internal

APNICRANDNET-TUI-AU is held by APNIC Research and Development.

What it's used for

  • The space carries internal research infrastructure, evidenced by the netname APNIC-RD and registrant APNIC Research and Development.
  • The AS announces 512 IPv4 addresses across 1 prefix with 1 observed neighbour, indicating a small, isolated internal estate rather than a transit or access network.

Notable

  • The registrant APNIC Research and Development aligns directly with the AS handle APNICRANDNET-TUI-AU, confirming the space is owned by the registry's R&D division.
  • The address inventory consists of a single /23 block (203.147.108.0/23), which is finely subdivided for internal use within the APNIC organization.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-31, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 447 networks and 1,843 prefixes, as published 2026-11-01. 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.
