Summary

X-HOST

Ukraine · AI-generated

hosting business ukraine

X-HOST is operated by Rostilo Sergey Alexandrovich, a Ukrainian individual business owner.

What it's used for

  • The space carries hosting services, indicated by the netname X-HOST and the reverse DNS entry s26.x-host.net.ua.
  • The AS announces a single IPv4 prefix, 193.200.255.0/24, comprising 256 addresses, with 0 IPv6 prefixes.
  • With only 1 observed neighbour, the network functions as a small, isolated hosting or business endpoint rather than a transit provider.

Notable

  • The RDAP registrant matches the AS handle and the physical person listed in the registry, confirming direct ownership by the individual.
  • The address inventory consists of a single /24 block, representing a compact and self-contained network footprint.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-28, 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 1,851 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.
