Summary

Kuroit

United Kingdom · AI-generated

hosting vps dedicated uk

KUROIT is operated by Kuroit Limited.

What it's used for

  • The address space carries virtual private servers and dedicated hosting infrastructure, evidenced by reverse DNS entries such as uk.kuroit.com and netnames like Kuroit.
  • The AS announces 2304 IPv4 addresses across 9 prefixes and 2 IPv6 prefixes, with 4 observed routing neighbours.
  • Traffic from this AS consists of web hosting, VPS instances, and dedicated server endpoints for customers in the UK and internationally.

Notable

  • Registrants for the majority of prefixes are Kuroit NOC or Kuroit Limited, aligning with the AS holder.
  • Two prefixes, 46.37.124.0/24 and 91.205.158.0/24, show registrants Blackbridge Limited and The national operator of wireless communication "WiMAX-Ukraine" respectively, indicating leased or inherited space.
  • The inventory includes two prefixes registered to Private Customer, which do not fit the primary Kuroit branding.

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.
