Summary

Aalborg Airport

Denmark · AI-generated

airport business denmark

The AS handle AAL is held by Aalborg Lufthavn A.M.B.A., the operator of Aalborg Airport in Nørresundby, Denmark.

What it's used for

  • The address space carries internal airport infrastructure, evidenced by the netname DK-AAL-20051129 and registrants Aalborg Lufthavn IT and Aalborg Lufthavn A.M.B.A.
  • The inventory consists of 256 IPv4 addresses in a single /24 prefix (89.39.123.0/24) with 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider
  • Traffic from this AS represents internal operations for the airport, including IT systems, office workers, and facility management endpoints

Notable

  • Registrants align with the announcer, listing Aalborg Lufthavn IT and Aalborg Lufthavn A.M.B.A. for the sole announced prefix
  • The address inventory is a single contiguous /24 block, typical for a site-specific corporate estate with no subdivision into multiple prefixes

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: 448 networks and 1,851 prefixes, as published 2026-11-03. 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.
