Unclassified APNIC Cable/DSL/ISP
Summary
East Cork Broadband
isp telecom infrastructure
Five blocks collected one at a time over a decade, one of them registered on the last day of a year.
What it's used for
- A rural broadband provider. Five IPv4 prefixes and one IPv6
/32announced from Ireland, four thousand addresses, through one observed BGP neighbour.
Notable
- Every netname follows the same pattern of country code, a four letter abbreviation of the company, and the allocation date, so the set reads as a timeline.
- Those dates are spread across more than a decade, and one of them falls on the final day of its year.
- All nine answering addresses use one form: the full address with dashes under the company's domain.
- Fifteen addresses were queried for reverse DNS and nine returned a name.
- One observed neighbour carries all four thousand addresses.
Interesting
- Acquiring address space in small pieces years apart is what a growing rural provider does. Each block is a round of subscribers that the previous block could no longer hold.
- Naming every address the same way is the practical choice for a network whose customers are homes. The name identifies the line without identifying the household.
- The single upstream is the real constraint. A provider serving a region with one path out has no answer to that path failing, and rural networks are where that hurts most.

Reputation
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: 440 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.
