Summary

SecurityNet.cz

Czechia · AI-generated

hosting business czechia

SECURITYNET-AS is operated by SecurityNet.cz s.r.o.

What it's used for

  • The address space carries web hosting and business services, evidenced by reverse DNS entries such as hukot.cloud, ishost.cz, and solarworldlafric.com, alongside the netname CZ-SECURITYNET-CZ-20180703.
  • The AS announces 3072 IPv4 addresses across 5 prefixes and 2 IPv6 prefixes, with only 1 observed neighbour, indicating a small-scale access or hosting network rather than a transit provider.
  • Traffic from this AS consists of web hosting endpoints, SEO-optimized websites, and e-commerce platforms provided to small and medium-sized businesses in the Czech Republic.

Notable

  • Registrants for the largest prefixes include GTT a.s. for 46.36.36.0/22, 46.36.40.0/23, and 46.36.44.0/24, while SecurityNet.cz s.r.o. holds 176.102.64.0/22, suggesting a mix of leased and owned address space.
  • The inventory includes a large IPv6 block 2a07:dbc0::/32 alongside a smaller 2a02:25b0:aaaa::/48, reflecting a dual-stack deployment strategy.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-01, 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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
