Summary

DFS Deutsche Flugsicherung GmbH

Germany · AI-generated

government aviation corporate infrastructure

The AS handle DFS is held by DFS Deutsche Flugsicherung GmbH.

What it's used for

  • The address space carries internal corporate infrastructure for Germany's air navigation service provider, identified by the netname DFS-NET across all announced prefixes.
  • The inventory consists of 3072 IPv4 addresses across 10 prefixes and 1 IPv6 prefix, with only 3 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.
  • Traffic from this AS consists of internal operations for air traffic control, including systems supporting airspace management and aviation data services for German airports.

Notable

  • All registrants for the announced prefixes are listed as DFS Deutsche Flugsicherung GmbH, fully consistent with the AS holder.
  • DFS is a state-owned company under private law, 100% owned by the German federal government, responsible for air traffic control in Germany.
  • The address inventory is finely subdivided into multiple /24 and /23 blocks, reflecting site-by-site segmentation typical of a large internal 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: 436 networks and 1,769 prefixes, as published 2026-10-13. 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.
