Summary

Ninetreehill Broadband

Ireland · AI-generated

isp residential ireland broadband

The AS handle NTHILL-AS is held by Ninetreehill Broadband Ltd.

What it's used for

  • The address space carries residential broadband traffic, evidenced by the netname NTHILL associated with both announced prefixes.
  • The network announces 2304 IPv4 addresses across 2 prefixes and maintains a single observed neighbour, a ratio that indicates an access or eyeball network rather than a transit provider.
  • As a local Irish broadband provider based in Kildare, the traffic from this AS consists of subscriber internet access for residential customers in the Moone area.

Notable

  • The registrants for both prefixes, 178.216.112.0/21 and 91.216.6.0/24, are consistently listed as Ninetreehill Broadband Ltd, matching the AS holder.
  • The address inventory is compact, consisting of one /21 and one /24 block, which is typical for a small regional ISP serving a specific local community.

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 1,779 prefixes, as published 2026-10-24. 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.
