Summary

kapper.net

Austria · AI-generated

hosting isp residential business

KAPPERNET is operated by KAPPER NETWORK-COMMUNICATIONS GmbH.

What it's used for

  • The address space carries a mix of corporate and third-party registrations, including netnames for AT-KAPPERNET, AT-FLASHBROTHER, AT-AIP, Christoph-Schmoigl-edvUNION, WYRU-ASC, AT-FUNKINTERNET, and WT-APPLICATION.
  • The AS announces 13,056 IPv4 addresses across 11 prefixes and 2 IPv6 prefixes, maintaining 36 observed neighbours.
  • As a Vienna-based provider offering hosting, housing, and internet solutions, the traffic comprises a blend of datacenter endpoints, corporate office users, and residential subscribers.

Notable

  • Registrants for the majority of prefixes align with the announcer, listing kapper.net admin and KAPPER NETWORK-COMMUNICATIONS GmbH, while other blocks are registered to entities such as flashbrother.net KG, Ambient Information Processing GmbH, and funkinternet at ISP GmbH.
  • The inventory consists of a large /19 block alongside numerous smaller /22, /23, and /24 prefixes, indicating a diverse address estate rather than a single contiguous allocation.

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: 432 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.
