Summary

Autodesk

United States · AI-generated

enterprise business infrastructure

More than half the address space belongs to a subsidiary on the other side of the world, registered through a different registry.

What it's used for

  • A software company's corporate network. 79,104 addresses across 15 IPv4 prefixes, with six observed BGP neighbours and no IPv6 announced.

Notable

  • 147.176.0.0/16 carries the netname AUTODESKLTDJAPAN-JP and an incident-response object named IRT-AUTODESKLTDJAPAN-JP.
  • The remaining thirteen 132.188 prefixes all carry the netname AUTODESK, registered to Autodesk, Inc. with a hostmaster contact.
  • Those thirteen run from /20 down to two adjacent /24s, 132.188.70.0/24 and 132.188.71.0/24.
  • 203.202.234.0/24 is the fifteenth prefix.
  • Eighteen addresses were queried for reverse DNS and none returned a name.

Interesting

  • One block holds most of the 79,104 addresses, and it is the subsidiary's rather than the parent's. Regional offices that registered early sometimes hold more space than the head office ever needed, because the head office started asking later, when the answers had got smaller.
  • The 132.188 range is announced as thirteen pieces down to a pair of adjacent /24s. Splitting two consecutive blocks rather than announcing one /23 is a routing decision, not an allocation one: the two halves go somewhere different.
  • An incident-response object exists on the subsidiary's block and not on the parent's. The registry that issued it requires one; the registry that issued the rest does not.

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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
