Summary
Drei Austria
mobile isp residential austria
The AS handle H3G-AUSTRIA-AS is operated by Hutchison Drei Austria GmbH, a major Austrian mobile and fixed-line telecommunications provider.
What it's used for
- The address space carries mobile and fixed-line customer traffic, evidenced by reverse DNS entries such as
77.116.128.0.wireless.dyn.drei.comand netnames likeH3G-CUSTOMERS-NET. - With 575,232 IPv4 addresses announced across 34 prefixes and 49 observed neighbours, the high address-to-neighbour ratio indicates an access network serving end-users rather than a transit provider.
Notable
- Registrants consistently identify the operator as Hutchison Drei Austria GmbH or its administrative arms, such as "Hutchison 3G Austria Admin" and "H3A IP Network Systems," aligning with the AS holder.
- On 31 October 2017, Hutchison Drei Austria completed the acquisition of Tele2 Austria, integrating its network and customer base into the Drei brand.
- The inventory includes large blocks like 77.116.0.0/15 and 178.112.0.0/15, alongside smaller subdivisions, reflecting a mature, segmented corporate estate for a national carrier.

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 1,775 prefixes, as published 2026-10-11. 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.
