Summary

Santos Limited

Australia · AI-generated

business corporate adelaide multi-homing

SANTOS-MULTIHOME-AS-AP is the autonomous system for Santos Limited, a major Australian energy company headquartered in Adelaide.

What it's used for

  • The address space is registered under netnames SANTOSNET-1-AU, SANTOS-AU, SANTOS-AP, and SANTOSNET, all assigned to Santos Limited.
  • The AS announces 1536 IPv4 addresses across 5 prefixes and maintains 2 observed neighbours, indicating a small, internally segmented corporate estate rather than a transit or access network.
  • Traffic from this AS consists of internal corporate communications, office workers, and business endpoints for the energy company's operations.

Notable

  • All registrants for the announced prefixes are Santos Limited, consistent with the AS holder.
  • The address inventory is finely subdivided into five distinct /24 and /23 blocks, reflecting site-by-site segmentation typical of a large corporate network.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
