Summary

isp telecom infrastructure
Some reverse names quote a range these addresses do not belong to.
What it's used for
- A national carrier's regional branch. Twelve IPv4 prefixes announced from the Russian Federation, no IPv6, fifteen thousand addresses, across five observed BGP neighbours.
Notable
- Reverse names put the last octet first, then a label built from the word for network and the address's own leading octets, then a city domain:
254.net-94.242.149.kaluga.ru. - Two answering addresses break that rule. The address 109.225.32.128 answers with
128.net-94.242.32.kaluga.ru, naming a range it is not in, and the neighbouring block does the same. - One block uses a shorter form with only the third octet, so three naming schemes coexist in one zone.
- Eight of the twelve blocks share a single netname written in capitals with an underscore, describing a regional centre; the other four use the parent company's code and an allocation date.
- Eighteen addresses were queried for reverse DNS and seven returned a name.
Interesting
- Those mismatched names are a template copied to a new range and never edited. Anyone using reverse DNS to work out where an address sits would be sent to the wrong network.
- Twelve routes ranging from a
/19down to five separate/24blocks is a network assembled from whatever was available, over years, rather than planned. - No IPv6 at all from a branch of a national carrier is the gap worth naming here.

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: 445 networks and 1,817 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.
