Summary

Rostelecom Tambov

Russia · AI-generated

isp telecom business

A broadcast address with its own reverse name, in a zone that still says dialup.

What it's used for

  • The Tambov regional branch of a Russian national operator. 10,496 addresses across nine IPv4 prefixes, three observed BGP neighbours, and no IPv6 announced.

Notable

  • Six of 18 sampled addresses returned names, spread across several domains under one regional label: static-139-254.pppoe.tmb.ru, net-130-0.net.tmb.ru, bcast-131-255.b22.dialup.tmb.ru, net-145-0.tmb.ru, relay1.planeta-tmb.ru and mail.tmb.rss.ru.
  • Netnames are MACROREGIONAL_CENTER, ROSTELECOM-NET and ROSTELECOM-NET2.
  • The AS handle is RT-TMB-AS PJSC Rostelecom. Tambov branch, ending in a sentence full stop.
  • One prefix could not be looked up in the registry; the fetch failed.

Interesting

  • bcast in a hostname marks the broadcast address of a subnet, the one address that cannot be assigned to a host. Naming it anyway is what happens when a zone is generated across a whole range without excluding the reserved ends, and it quietly reveals the subnet boundaries to anyone reading the names.
  • Two access technologies appear in the same set of names, one of them long superseded. Zones outlive the equipment they describe.
  • MACROREGIONAL_CENTER uses underscores and describes an internal organisational tier rather than the network. It is the parent company's own structure leaking into the public registry.

Exchange presence is recorded rather than inferred: the directory collected by Packet Clearing House (https://www.pch.net/ixp/data) on 2026-11-12, 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: 455 networks and 1,849 prefixes, as published 2026-11-13. 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.
