Summary

First Ukrainian Internet Registrar

Ukraine · AI-generated

hosting registrar ukraine

HBUA-AS is operated by First Ukrainian Internet Registrar LLC.

What it's used for

  • The address space carries hosting infrastructure, evidenced by reverse DNS entries such as colo-198-128.hostbizua.com and uahoster.com, and netnames FUIR-MNT and HOSTBIZUA-NET.
  • The AS announces 768 IPv4 addresses across 2 prefixes with 1 observed neighbour, indicating a small-scale hosting or registrar network rather than a transit provider.
  • Traffic from this AS consists of web hosting services and registrar-related endpoints for Ukrainian internet users.

Notable

  • Registrants for both announced prefixes are First Ukrainian Internet Registrar LLC, matching the AS holder.
  • The address inventory is compact, consisting of two /24 and /23 blocks, typical for a specialized registrar or small hosting provider.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

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: 447 networks and 1,843 prefixes, as published 2026-11-02. 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.
