Summary

Blackrock Clinic

Ireland · AI-generated

business healthcare private dublin

The AS handle BC-AS is held by Blackrock Clinic Unlimited Company.

What it's used for

  • The address space carries the private hospital's internal network, evidenced by netnames IE-BLACKROCKCLINIC-20050203 and IE-BLACKROCKCLINIC-20220413 and registrants including "Blackrock Clinic RIPE Administrator" and "Blackrock Clinic RIPE IT".
  • The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained corporate estate rather than a transit or access provider.
  • Traffic from this AS consists of internal hospital systems, administrative endpoints, and clinical infrastructure for the private hospital located in Blackrock, Dublin.

Notable

  • Registrants for both announced prefixes align with the AS holder, listing "Blackrock Clinic Unlimited Company" and associated RIPE administrative roles.
  • The address inventory is compact, consisting of two /24 IPv4 blocks and a single /29 IPv6 block, consistent with a single-site corporate deployment.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
