Hosting RIPE Content
Summary
Alwyzon
hosting business austria
ALWYZON is the autonomous system for Alwyzon, a trading name of Hohl IT e.U.
What it's used for
- The address space carries server hosting infrastructure, evidenced by reverse DNS entries such as
w1.j-gloede.de,strg-movies, andservfail.deenes.at. - The AS announces 5,632 IPv4 addresses across 14 prefixes and maintains 437 observed neighbours, a ratio indicative of a hosting provider with significant peering relationships rather than a large residential access network.
- Traffic from this AS consists of web and API endpoints, virtual servers, and storage services operated by Hohl IT e.U. in Vienna, Austria.
Notable
- Registrants for the majority of prefixes are consistent with the announcer, listing
Alwyzon NOC; Hohl IT e.U.; Abuse-C Role, though two prefixes (46.37.113.0/24and132.243.203.0/24) show different netnames (IPXOandInterLIR-Marketplace). - The address inventory is finely subdivided into 14 distinct IPv4 prefixes, reflecting a corporate estate segmented by acquisition or service type rather than a single contiguous block.

Classification and threat
Hosting Datacenter or cloud provider. Addresses are servers, not people.
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: 453 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.
