Summary

Arden Broadband

Ireland · AI-generated

residential rural broadband ireland

ARDEN-AS is operated by Arden Broadband Ltd.

What it's used for

  • The address space carries rural broadband services, with netnames IE-EURONA-BRISKNET-20120615 and ARDEN-NET indicating legacy and current infrastructure.
  • The AS announces 6144 IPv4 addresses across 3 prefixes and maintains a single observed neighbour, a ratio characteristic of an access network providing last-mile connectivity rather than transit.
  • Traffic from this AS consists of residential subscriber traffic for rural fibre and wireless broadband services in Ireland, specifically in Cavan and Roscommon.

Notable

  • Registrants include Eurona-Brisknet Ltd for the 5.83.240.0/20 block and Arden Broadband Ltd for the 91.235.96.0/22 and 185.129.132.0/22 blocks, reflecting the operator's history involving the Brisknet brand.
  • The address inventory is small and segmented into three distinct prefixes, consistent with a regional rural broadband provider rather than a large national ISP.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-13, 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: 442 networks and 1,773 prefixes, as published 2026-10-13. 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.
