Summary

TutHost

Ukraine · AI-generated

hosting residential ukraine

The AS handle TUTHOST is held by Denis Pavlovich Semenyuk.

What it's used for

  • The address space carries hosting and residential services, evidenced by the netname TutHost and reverse DNS entries like host-64.svai.net.
  • The network announces 1280 IPv4 addresses across 2 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 and residential broadband users in Ukraine.

Notable

  • Registrants for the two prefixes differ: 91.203.4.0/22 is registered to Denis Pavlovich Semenyuk under the netname TutHost, while 91.216.106.0/24 is registered to PE Poluden V.M. under the netname SVAI-NET.
  • The inventory is small and fragmented, consisting of one /22 and one /24 block, typical of a small Ukrainian ISP or hosting provider.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
