Summary
Tavria-V
business isp enterprise
The brand, a single letter and a country code, run together into one word that reads three ways.
What it's used for
- A company's own network. A single IPv4 prefix announced from Ukraine, no IPv6, two hundred and fifty-six addresses, through one observed BGP neighbour.
Notable
- The holder field is a place name, a hyphen, a single letter, and the suffix for a limited company. The letter carries no explanation anywhere in the record.
- The AS handle glues the place name, that letter and a two-letter country code into one string, with no separator to say where any of the three ends.
- The netname is the same glued string plus the word for a network, so the ambiguity is repeated rather than resolved.
- The block is registered to the company itself and to an abuse contact, with nothing else attached.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Handles like this are written once, by somebody who knows what every character means, and then read for years by people who do not. The country code at the end is the only part a stranger can decode with confidence, and even that could be the start of the next word.
- One smallest-routable block and one upstream is the minimum viable independent presence. A company takes it on when the addresses matter more than the bandwidth, because the addresses are the part that stays the same when the provider changes.

Internet exchanges
No exchange port on file. Many exchanges publish no participant list, so this is not proof of absence.
Transit providers
1 upstream, 0 downstream and 1 adjacent networks observed; most-used upstreams first.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-14, 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 2026-11-14. 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.
