isp residential ukraine access

The AS handle UNET-AS is held by FOP Lisovskiy Dmitro Sergiyovich.

What it's used for

  • The address space carries residential and business access traffic, evidenced by reverse DNS entries such as ip-91.225.141.0.u-net.com.ua and 185-15-6-128.pool.ic.km.ua.
  • The network announces 1536 IPv4 addresses across 2 prefixes with 3 observed neighbours, a ratio indicative of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for end-users in Ukraine, utilizing the u-net.com.ua and pool.ic.km.ua domains for host identification.

Notable

  • Registrants for the announced prefixes include FOP Lisovskiy Dmitro Sergiyovich for 91.225.140.0/22 (netname UNET-NET) and KhmelnitskInfocom LTD for 185.15.6.0/23 (netname UA-IC).
  • The address inventory is split between two distinct registrants, suggesting a combination of directly owned space and leased or partner-provided blocks.

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: 454 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.
