Summary

Russian Federation · AI-generated

hosting vps russia

SCULKSOFT-AS is held by Sculk Software LLC.

What it's used for

  • The address space carries VPS and dedicated server infrastructure, evidenced by reverse DNS entries pointing to hostingsecurityes.com and the netname SCULKLTD.
  • The AS announces 512 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 5 observed neighbours, indicating a small-scale hosting provider rather than a transit or large access network.
  • Traffic from this AS consists of web servers, API endpoints, and virtual private servers hosted for clients, consistent with the company's business of providing VDS/VPS hosting and dedicated servers.

Notable

  • Registrants for the two announced IPv4 prefixes differ: 91.199.230.0/24 is registered to Ecode Administrative while 95.214.92.0/24 is registered to Sculk Ltd., suggesting the former may be leased space or a separate administrative entity.
  • The address inventory is small and finely subdivided, with only two IPv4 prefixes announced, typical of a boutique 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: 453 networks and 1,854 prefixes, as published 2026-11-06. 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.
