FRAPORT is the autonomous system for Fraport AG Frankfurt Airport Services Worldwide.

What it's used for

  • The space carries internal airport infrastructure, identified by the netname FAIRNET and registrant Fraport AG Frankfurt Airport Services Worldwide.
  • The AS announces 65536 IPv4 addresses within a single /16 prefix (146.234.0.0/16) and one IPv6 prefix (2a04:5740::/29).
  • With only 3 observed neighbours, the network functions as an internal corporate estate for the airport operator rather than a transit or access provider.
  • Traffic from this AS consists of operational systems, office workers, and infrastructure endpoints supporting Frankfurt Airport operations.

Notable

  • The registrant Fraport AG Frankfurt Airport Services Worldwide matches the AS holder, confirming direct ownership of the address space.
  • The inventory consists of a single contiguous IPv4 block and one IPv6 prefix, indicating a consolidated internal network design.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-12, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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.
