Summary

Flughafen München GmbH

Germany · AI-generated

airport business infrastructure germany

The AS handle MUNICH-AIRPORT-AS is held by Flughafen München GmbH, the operator of Munich Airport.

What it's used for

  • The address space carries internal corporate infrastructure, evidenced by netnames MUNAIR and DE-MUCAIRPORT-20180423 and registrants including FMG IT Service and FMG Customer Service.
  • The AS announces 66,560 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 2 observed neighbours, indicating a self-contained internal network rather than a transit or access provider.

Notable

  • Registrants align with the announcer, listing FMG ADMIN AND HOSTMASTER, Flughafen Muenchen GmbH, and FMG IT Service for the primary block.
  • The inventory consists of one large /16 block and one smaller /22 block, reflecting a finely subdivided internal corporate estate for site-by-site segmentation.

Reputation

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
