Summary

Halifax International Airport Authority

Canada · AI-generated

airport business canada leased

HIAA-NS is the autonomous system for the Halifax International Airport Authority.

What it's used for

  • The space carries Eastlink public infrastructure, as evidenced by the netname EASTLINK-EASTLINK-CORP-HIAA-86 and reverse DNS entries pointing to public.eastlink.ca.
  • The AS announces a single IPv4 prefix of 256 addresses with 2 observed neighbours, indicating a small, dedicated site connection rather than a transit or large-scale access network.

Notable

  • The registrant Eastlink HSI differs from the AS holder, indicating the address space is leased from Eastlink for the airport's use.
  • The inventory consists of a single /24 block, representing a compact, single-site allocation for the airport authority.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-18, 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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
