Unclassified RIPE
Summary
Merezha
isp business hosting
Every field in the record is the same single word, and the handle spells out what an AS is in lower case.
What it's used for
- A provider. A single IPv4 prefix announced from Ukraine, no IPv6, five hundred and twelve addresses, through two observed BGP neighbours.
Notable
- The AS handle is the brand in capitals, then the brand again in ordinary case, then the words autonomous system spelled out in lower case, describing the object rather than naming it.
- The netname is the brand alone. The holder field is the brand plus a legal form. Three fields, one word.
- The whole holding is a single block of two smallest-routable ranges joined together, which is an unusual size to hold and nothing else.
- The block is registered to the company and a role for abuse, with no operations contact and no maintainer named.
- Three addresses were queried for reverse DNS and none returned a name.
Interesting
- Spelling out autonomous system inside an autonomous system's own handle is the same instinct that writes the word bank on the outside of a bank. The field was free text for years, and some operators filled it in for a human reader who was never going to arrive.
- Five hundred addresses and two upstreams is a provider serving a specific set of customers rather than a market. The second connection is the entire redundancy plan.

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 2026-10-28, 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: 448 networks and 1,851 prefixes, as published 2026-10-29. 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.
