Summary

KRAXNET s.r.o.

Czechia · AI-generated

hosting business czech

KRAXNET-AS is operated by KRAXNET s.r.o.

What it's used for

  • The address space carries hosting and domain management services, evidenced by the netname KRAXNET and reverse DNS entries like unn-178.217.242.0.kraxnet.cz.
  • The AS announces 2048 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small-scale hosting or business network rather than a transit provider.
  • Traffic from this AS consists of web hosting, domain registration, and related online services provided to business clients.

Notable

  • The registrant KRAXNET s.r.o. matches the AS holder, confirming consistent ownership.
  • The address inventory is compact, consisting of a single /21 IPv4 block and a single /48 IPv6 block, typical for a specialized hosting provider.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-29, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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: 448 networks and 1,849 prefixes, as published 2026-10-29. 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.
