Summary

Hvosting

Ukraine · AI-generated

hosting business ukraine

The AS handle HVOSTING-AS is held by PE Konstantin Vladimirovich Kravchenko, operating under the brand Hvosting.

What it's used for

  • The address space carries hosting infrastructure, evidenced by the netnames HVOSTING-NET and HVOSTING2-NET and the reverse DNS entry 254.dc42.dit-systems.com.
  • The AS announces 2048 IPv4 addresses across 2 prefixes and maintains 2 observed neighbours, a ratio consistent with a small-scale hosting or business provider rather than a transit carrier.
  • Traffic from this AS consists of web and API endpoints for hosting clients, as indicated by the "Hvosting" branding and the presence of a Solana validator node in Kyiv.

Notable

  • Registrants for both announced prefixes align with the AS holder, listing PE Konstantin Vladimirovich Kravchenko and the Hvosting.UA hostmaster.
  • The inventory consists of two /22 blocks, 91.200.40.0/22 and 91.225.136.0/22, with no IPv6 prefixes announced.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-16, 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: 442 networks and 1,783 prefixes, as published 2026-10-17. 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.
