About this network

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.
