residential isp wisp regional

WESTNET-IE is operated by Westnet Broadband Mayo Limited.

What it's used for

  • The address space carries residential customer traffic, evidenced by reverse DNS entries such as 254-119.cust.westnet.ie and 64-184.cust.cpcns.ie.
  • The AS announces 10,496 IPv4 addresses across 4 prefixes and 2 IPv6 prefixes, while maintaining 11 observed neighbours; this ratio of address space to peering partners indicates an access network serving local subscribers rather than a transit provider.
  • Traffic consists of broadband subscriber eyeballs for residents in County Mayo and the wider West of Ireland, delivered via fibre, DSL, and wireless technologies.

Notable

  • Registrants for all announced prefixes consistently identify WESTNET BROADBAND MAYO LIMITED and Island Bridge Networks Network Operations, aligning with the AS holder.
  • The address inventory includes a mix of blocks acquired between 2005 and 2019, with netnames like IE-WESTNET-BB-20051207 and IE-WESTNET-BB-20190927 reflecting the phased expansion of the regional service.

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: 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.
