Summary
Three Ireland
mobile isp telecom
154,880 addresses in fifty-four separate announcements, and not one IPv6 route.
What it's used for
- The mobile network of an Irish operator. 154,880 addresses across fifty-four IPv4 prefixes, eighteen observed BGP neighbours, and no IPv6 announced.
Notable
- The largest blocks are
92.251.128.0/17,31.200.128.0/18and178.167.128.0/18. - Netnames mix dated and undated forms:
IE-H3G-20060504,IE-H3G-20071123,IE-H3G-20100317,IE-H3G-20110428,H3G-IEandH3GIE-SUBS3. - Every block lists role objects named
ROI AdminandROI Tech. - Sampled names read
92.251.160.0.threembb.ie, the four octets written forward with no separator before the domain.
Interesting
- A handset network of this size with no IPv6 route at all is the most expensive way left to run a mobile operator. Every subscriber has to be squeezed behind shared addresses, and the fifty-four fragments are the record of buying more IPv4 in whatever pieces were available, year after year.
- The reverse names are an address with a domain glued to the end, so the hostname reads like a sentence that changed its mind. It parses fine and it carries no information the address did not already carry.
SUBS3in one netname marks a subscriber pool, and the numbered suffix implies at least two others before it. The registry is being used as an internal inventory of pools here, not just as a record of who holds what.

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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
