Summary
BT Ireland
isp legacy
The Irish network of BT (AS-BTIRE), which grew out of a lineage of pioneering Irish providers: IEUnet, EUnet Ireland, and Esat Net.
What it's used for
- Broadband, business connectivity, and transit across Ireland as part of BT Group.
Notable
- A large eyeball and enterprise network, not a small hosting operation.
Interesting
- The lineage traces to IEUnet, one of Ireland's first commercial internet providers in the early 1990s, which explains the low AS number.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
