Summary
TANAID LLC
isp legacy
TANAID is a small Ukrainian telecommunications company, LLC TANAID, registered in the Balakliia area of Kharkiv oblast in November 2010. Its registered activity is telecommunications (NACE 61.90), and it operates under the domain tanaid.net.ua.
What it's used for
This is one of the smallest networks in its range. TANAID announces a single /22 — 91.231.148.0/22, about 1,024 usable addresses — with no IPv6 and exactly one observed BGP neighbour. A single prefix behind a single upstream is the routing profile of a local access provider serving one area, not a carrier or a hosting operation.
The prefix was first seen in BGP in October 2011, which lines up neatly with the company's 2010 registration. Unusually for a low-numbered AS, the number and the operator appear to be roughly contemporaries here rather than the AS being an early allocation later reissued.
Notable
- No PTRs were returned on any of the addresses sampled inside the announced prefix. That is not proof the reverse zone is undelegated, but it does mean there is no direct evidence in the pack of what the space carries. The classification rests on the operator's registered business and its routing shape, so treat it as provisional.
- Kharkiv oblast has been a front-line region since 2022. Small regional Ukrainian ISPs of this size have had a difficult operating environment, and a single-prefix, single-upstream network has no redundancy to fall back on.

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 2026-11-12, 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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
