Summary

Airbus Defence and Space

France · AI-generated

business defence aerospace corporate

The AS handle INTESPACE is held by Airbus Defence and Space SAS.

What it's used for

  • The address space carries corporate infrastructure for a major aerospace and defence manufacturer, as indicated by the netname INTESPACE and registrant Airbus Defence and Space SAS.
  • The AS announces a single IPv4 prefix, 91.217.164.0/24, comprising 256 addresses, with one observed routing neighbour.
  • Traffic from this AS consists of internal corporate communications, engineering data, and secure communications services for government and military clients, rather than public internet access or transit.

Notable

  • The registrant Airbus Defence and Space SAS aligns with the AS holder, though the abuse contact references the former name Intespace.
  • The operator was formerly known as Intespace, a name retained in the AS handle and contact details following its integration into the Airbus Group structure.
  • The inventory is minimal, consisting of a single /24 block, which is typical for a specific site or internal network segment within a larger corporate estate.

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: 442 networks and 1,782 prefixes, as published 2026-10-16. 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.
