Summary

Auckland International Airport

New Zealand · AI-generated

airport business nz

AIALNET-NZ is operated by Auckland International Airport Limited.

What it's used for

  • The address space carries internal airport infrastructure, identified by the netname AIALNET-NZ and registrant AUCKLAND INTERNATIONAL AIRPORT LIMITED.
  • The AS announces a single IPv4 prefix, 203.176.188.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, this is a small, isolated network segment rather than a transit or access provider.
  • Traffic from this AS consists of internal corporate and operational systems for the airport, including office workers, IT endpoints, and facility management systems.

Notable

  • The registrant AUCKLAND INTERNATIONAL AIRPORT LIMITED matches the AS handle AIALNET-NZ, confirming direct ownership.
  • The address inventory is minimal, consisting of a single /24 block, which is typical for a dedicated corporate site network.

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: 449 networks and 1,846 prefixes, as published 2026-11-02. 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.
