Summary
FOP Kukanov Vitaly Yurievich
isp residential ukraine small
ASULTRANET is operated by FOP Kukanov Vitaly Yurievich, a Ukrainian sole proprietorship.
What it's used for
- The address space carries residential and small business internet access, evidenced by the netname
UNTRANETassociated with the primary /22 block. - The AS announces 1536 IPv4 addresses across 3 prefixes while maintaining only 3 observed neighbours, a ratio indicative of a local access provider rather than a transit carrier.
- Traffic from this network consists of subscriber eyeballs in the Chernihiv region of Ukraine, serving end-user devices connected to the local ISP infrastructure.
Notable
- Registrants are mixed: the largest block (91.225.196.0/22) is registered to FOP Kukanov Vitaly Yurievich, while the two /24 blocks (212.86.103.0/24 and 212.86.112.0/24) are registered to Netassist Limited under the netname
GI-NETASSIST-19991110. - The address inventory is small and fragmented, consisting of one /22 and two /24s, with no IPv6 prefixes announced.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-10-19, licensed CC BY-NC-SA 3.0. Transit is inferred from observed BGP paths, never declared by either party.

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 1,783 prefixes, as published 2026-10-20. 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.
