Summary

FlightSafety International

United States of America · AI-generated

aviation training corporate business

The AS handle FSI is held by FlightSafety International.

What it's used for

  • The address space carries corporate infrastructure for an aviation training provider, as indicated by the netname FSI-INETBLCK and registrant FlightSafety International.
  • The AS announces 1280 IPv4 addresses across 4 prefixes with only 2 observed neighbours, a ratio consistent with an internal corporate estate rather than a transit or access network.

Notable

  • All four announced prefixes share the same netname FSI-INETBLCK and registrant FlightSafety International, confirming a single, unified ownership structure.
  • The address inventory consists of four contiguous /24 and /23 blocks within the 66.109.0.0/16 range, reflecting a finely subdivided internal network design.

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 1,778 prefixes, as published 2026-10-20. 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.
