Summary

Department of Climate Change, Energy, the Environment and Water

Australia · AI-generated

government network australia

DECC-AS-AP is operated by the Department of Climate Change, Energy, the Environment and Water.

What it's used for

  • The address space carries internal government network traffic, identified by the netname EVIRONMENTNET and registrant Office of Environment and Heritage.
  • The AS announces 2048 IPv4 addresses across 3 prefixes with 2 observed neighbours, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic consists of internal communications and services for the Australian federal government's environmental and climate change portfolio.

Notable

  • Registrants for all announced prefixes list Office of Environment and Heritage, reflecting the department's previous name before its 2022 rebranding.
  • The Australian government renamed the Department of Environment and Climate Change to the Department of Climate Change, Energy, the Environment and Water in 2022.
  • The inventory consists of three contiguous IPv4 blocks within the 141.243.0.0/16 range, with no IPv6 prefixes announced.

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.
