Summary
MTS Vologda
isp telecom business
Reverse names with the octets written backwards, under a domain belonging to a company since absorbed.
What it's used for
- A regional network of a Russian mobile and fixed-line operator, serving the Vologda area. 21,504 addresses across seven IPv4 prefixes, one observed BGP neighbour, and no IPv6 announced.
Notable
- Fourteen of 18 sampled addresses returned names of the form
0-104-65-176.vologda.comstar-r.rufor the address176.65.104.0. - Netnames are
VOLOGDA-STREAM-NET,VOLOGDA20-STREAM-NETandRU-MTU-20120711. - Two blocks still list a predecessor company as a registrant alongside the current operator.
- One prefix could not be looked up in the registry; the fetch failed.
Interesting
- The octets are written in reverse order, matching the layout of the reverse tree rather than the address itself. This is the second holder in this range to generate names that way, so it is a recognisable convention rather than a one-off mistake, and it means a name and its address read as mirror images.
- The domain belongs to a company that no longer exists independently, and its registry objects sit beside the acquirer's. Neither the zone nor the netnames were rewritten after the merger.
- One neighbour for 21,504 addresses is a regional arm reaching the internet entirely through its own parent's backbone.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
