Summary

hosting isp business
Four blocks over eighteen years, one upstream, and an operations contact under a different legal name.
What it's used for
- A hosting and network services company. Four IPv4 prefixes and one IPv6
/32announced from the Russian Federation, fifteen thousand three hundred and sixty addresses, through a single observed BGP neighbour.
Notable
- All four netnames follow the same template of country code, brand and date, and the dates span eighteen years from the year two thousand onwards.
- The blocks get smaller as the dates get later, from a
/20early on to a/22at the end, which is the registry tightening rather than the company shrinking. - Every block lists the company under one legal form and an operations centre under a different one, so the record names two entities sharing a brand.
- There is no separate abuse contact anywhere in the record.
- Twelve addresses were queried for reverse DNS and none returned a name.
Interesting
- A single upstream for fifteen thousand addresses is the most striking number here. It means every customer's reachability depends on one commercial relationship, which is cheap and works until it does not.
- Two legal forms behind one brand usually means an operating company and a licence holder. Which one appears in a registry field depends on who filled the form in, and the pair survives because nothing ever forces them to be reconciled.

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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
