Summary

isp telecom business transit
Three reverse-naming conventions on three unrelated domains, inside one network.
What it's used for
- A national operator's retail network. Two hundred IPv4 prefixes and twenty-six IPv6 prefixes announced from the Russian Federation, two hundred and sixty-eight thousand addresses, across eight observed BGP neighbours.
Notable
- One sampled name is the octets hyphenated with a leading label, then a three-letter regional code, then a word for a host, on the group's own domain.
- Another is the four octets in forward order with the dots kept, on
spark-ryazan.ru, a domain naming a different brand and a different city. - A third is the four octets reversed with the dots kept, on
uralttk.ru, a third domain naming a region. - The netnames are equally mixed: a predecessor company's name with a date, a city abbreviation joined to the group's initials, a client pool for a fourth brand, and the current company's abbreviation.
- The AS handle ends in the word for the retail side of the business.
- Of eighteen addresses queried, seven returned a name.
Interesting
- Two hundred and sixty-eight thousand addresses behind eight neighbours is a network that reaches its customers over its own long-distance infrastructure rather than through many interconnections.
- Every regional operator that was folded into this one kept its own domain and its own idea of how an address should be written. The merger reached the routing table years before it reached the naming.

Reputation
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: 431 networks and 1,775 prefixes, as published 2026-10-11. 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.
