About this network

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-20161118 and 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: 149.5.36.0/22 and 149.5.32.0/24 are registered to Cogent Communications, LLC (netname COGENT-149-5-16), while 185.58.16.0/22 is registered to Model Telecom Ltd (netname IE-MODELTELECOM-20140519); only 185.178.68.0/22 is 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.
