Summary
Carnsore Broadband
isp residential fibre ireland
CARNSOREBROADBAND is held by Carnsore Broadband Limited.
What it's used for
- The space carries fibre broadband access for residential customers in Wexford, Ireland, as indicated by the netname
IE-CARNSORE-20161118and the operator's self-description as a fibre broadband provider. - The AS announces 3,328 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with 13 observed neighbours; this ratio of modest address space to a moderate number of peers is consistent with a regional access network rather than a transit provider.
- Traffic from this AS consists of subscriber eyeballs using fibre broadband services in the Carnsore and Wexford area.
Notable
- Registrants do not fully agree with the announcer:
149.5.36.0/22and149.5.32.0/24are registered to Cogent Communications, LLC (netnameCOGENT-149-5-16), while185.58.16.0/22is registered to Model Telecom Ltd (netnameIE-MODELTELECOM-20140519); only185.178.68.0/22is registered to Carnsore Broadband Limited. - The address inventory is a mix of leased or historically allocated space from Cogent and Model Telecom alongside Carnsore's own allocation, suggesting the operator has grown by acquiring or leasing prefixes from other Irish providers.

Classification and threat
Residential Fixed-line consumer ISP. Addresses here are homes.
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: 445 networks and 1,817 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.
