Summary

Dobrobut

Ukraine · AI-generated

medical corporate ukraine

The AS handle DOBROBUT-AS is held by Dobrobut, a major Ukrainian medical network.

What it's used for

  • The space carries corporate infrastructure for a healthcare provider, evidenced by the netname Dobrobut-net and reverse DNS entries like drmpool0190.pptp.xsunet.net.ua.
  • The inventory consists of 256 IPv4 addresses within a single /24 prefix (194.110.6.0/24) and 0 IPv6 prefixes, with 1 observed neighbour, indicating a small, self-contained internal network rather than a transit or access provider.
  • Traffic from this AS represents internal operations for a medical organization that operates 20 medical centers and 2 multidisciplinary hospitals in Kyiv, including staff connectivity and internal systems.

Notable

  • The RDAP registrant matches the AS holder, identified as Company "Dobrobut" Association for Students, PhD Students and Doctors National Technical University.
  • The address inventory is a single contiguous /24 block, consistent with a dedicated corporate allocation for a specific organization.

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: 442 networks and 1,779 prefixes, as published 2026-10-23. 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.
