Unclassified RIPE
Summary

isp hosting business
The AS handle is five words run together with no spaces and a letter missing.
What it's used for
- A small provider's network. One IPv4
/24announced from Ukraine, no IPv6, two hundred and fifty-six addresses, across two observed BGP neighbours.
Notable
- The handle joins the letters for an autonomous system, the letters for information technology, a word for a centre missing its last letter, and two more words, all in capitals with nothing between them.
- The holder in the routing record is four initials after the abbreviation for a limited company, and nothing expands them anywhere in the record.
- The netname is a city and a country code run together as one word.
- The registrant is the same four-initial company and an abuse role written as a whole phrase ending in the name of the registry record type.
- Three addresses were queried for reverse DNS and one answered: four letters, a city contraction, and the business subdomain of the country's domain.
Interesting
- A single reverse name in a whole block, pointing at what looks like a building association's site, is the shape of a provider whose customers are addresses in a city rather than businesses on the internet.
- Running words together without separators is what happens when a field rejects spaces. The registry wants an identifier, the person filling it in wants a sentence, and the compromise is unreadable to both.

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 2026-10-27, 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: 447 networks and 1,852 prefixes, as published 2026-10-27. 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.
