airport business infrastructure ireland

DAA-AS-1 is held by DAA PLC, the commercial semi-state company that operates Dublin Airport.

What it's used for

  • The space carries internal corporate infrastructure, evidenced by the netname IE-DAAPLC-20170630 and registrants DAA-Networks Role and DAA-Abuse Role.
  • The AS announces a single IPv4 prefix, 91.214.173.0/24 (256 addresses), with 0 IPv6 prefixes and 2 observed neighbours.
  • This finely subdivided, single-prefix inventory against a low neighbour count indicates an internal corporate estate for airport operations rather than a public access or transit network.

Notable

  • Registrants align with the announcer, listing DAA-Networks Role, DAA PLC, and DAA-Abuse Role for the announced prefix.
  • DAA PLC was formerly known as the Dublin Airport Authority before rebranding to its current name.
  • The address inventory consists of a single /24 block, consistent with a dedicated corporate network segment.

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: 442 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.
