Summary

styrion

Austria · AI-generated

isp residential austria

STYRION is operated by styrion Holding GmbH.

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as 254-85-235-77.dyn-wll.styrion.net and 254-90-235-77.styrion.net.
  • The AS announces 3,840 IPv4 addresses across 4 prefixes in Austria, with only 1 observed neighbour, indicating a small access network rather than a transit provider.
  • Traffic consists of subscriber eyeballs for fixed-line internet access, consistent with the "dyn-wll" (dynamic wireless line) and standard host naming conventions in the reverse DNS.

Notable

  • Registrants for all announced prefixes are consistent with the announcer, listing styrion Holding GmbH and styrion Hostmasters.
  • The address inventory is compact and contiguous within the 77.235.0.0/16 range, subdivided into four distinct blocks.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-22, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
