Summary

Energex Limited

Australia · AI-generated

utility corporate infrastructure

ASN-ENERGEX-AP is held by Energex Limited.

What it's used for

  • The address space carries internal corporate infrastructure for a Queensland electricity distributor, as indicated by the netname ENERGEX-AU and registrants Energy Queensland SecOps and Energex Limited.
  • The AS announces 65536 IPv4 addresses across 10 prefixes with only 2 observed neighbours, a ratio that implies an internal corporate estate with site-by-site segmentation rather than a transit or access network.

Notable

  • All registrants agree with the announcer, consistently listing Energy Queensland SecOps and Energex Limited for every prefix in the inventory.
  • The address inventory consists of a single /17 block (147.209.0.0/17) subdivided into smaller prefixes, reflecting a finely segmented internal network structure.

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: 454 networks and 1,854 prefixes, as published 2026-11-06. 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.
