residential isp mts kaluga

STREAM-TV-KALUGA is operated by MTS PJSC.

What it's used for

  • The address space carries residential broadband traffic, evidenced by netnames such as RU-MTS-KALUGA-1, MTU-ADSL, and KLG-Comstar-r, and reverse DNS entries like ppp85-140-58-254.pppoe.mtu-net.ru.
  • The AS announces 4,608 IPv4 addresses across 7 prefixes with only 2 observed neighbours, a ratio characteristic of an access network serving local subscribers rather than a transit provider.
  • Traffic consists of subscriber eyeballs for MTS's mobile and fixed-line services in the Kaluga region, utilizing PPPoE and ADSL technologies.

Notable

  • Registrants for all prefixes are listed as MTS backbone NOC or MTS PJSC, which aligns with the announcer's identity as a regional division of the national carrier.
  • The inventory is composed of small /22, /23, and /24 blocks, reflecting a finely subdivided estate typical of a regional ISP managing local customer pools.

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: 448 networks and 1,849 prefixes, as published 2026-10-30. 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.
