Summary

Transpower New Zealand

Australia · AI-generated

utility transmission corporate infrastructure

TRANSPOWER-B-AS-AP is operated by Transpower New Zealand Ltd.

What it's used for

  • The address space carries corporate infrastructure for New Zealand's national electricity transmission grid, as indicated by the consistent TRANSPOWER-B netname and Transpower registrant across all prefixes.
  • The AS announces 16,640 IPv4 addresses across 6 prefixes with only 2 observed neighbours, a ratio that indicates an internal corporate estate rather than a transit or access network.
  • Traffic from this AS consists of office workers, engineering systems, and grid control endpoints supporting the maintenance and transmission of the electric power grid.

Notable

  • All registrants agree with the announcer, consistently listing Transpower as the registrant and TRANSPOWER-B as the netname.
  • The address inventory is finely subdivided into six distinct prefixes, reflecting site-by-site segmentation of the corporate network.
  • The country of announced blocks is listed as Australia, which aligns with the IRT contact IRT-TRANSPOWER-NON-NZ suggesting non-New Zealand address space allocation.

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

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: 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.
