residential isp ireland broadband

KERBB is operated by Ker Broadband Communications Ltd.

What it's used for

  • The address space carries residential broadband traffic, evidenced by netnames IE-KERNETBROADBAND-20190326 and IE-KERNETBROADBAND-20110520 registered to Ker Broadband Communications Ltd.
  • The AS announces 1536 IPv4 addresses across 2 prefixes with 1 observed neighbour, a ratio indicative of a local access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for the local community in Ballymacelligott, Co Kerry, Ireland.

Notable

  • Registrants for both announced prefixes agree with the AS holder, listing Ker Broadband Communications Ltd.
  • The address inventory is small and concentrated in two blocks: 2.59.104.0/22 and 91.228.24.0/23.

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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
