Summary

ER-Telecom Holding (Cheboksary)

Russian Federation · AI-generated

residential isp cheboksary russia

CHEB-AS is operated by JSC "ER-Telecom Holding", specifically its Cheboksary branch.

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by reverse DNS entries such as dynamicip-37-113-104-0.pppoe.cheb.ertelecom.ru and 109x195x247x255.static-business.cheb.ertelecom.ru.
  • With 41,216 IPv4 addresses announced across 17 prefixes and only 1 observed neighbour, the network functions as an access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs and business endpoints within the Cheboksary region, utilizing PPPoE and dynamic IP allocation for residential customers.

Notable

  • Registrants consistently identify JSC "ER-Telecom Holding" or its Cheboksary Branch, aligning with the AS holder.
  • The inventory is finely subdivided into /21 and /20 blocks, with netnames like ERTH-CHEB-PPPOE-10-NET indicating specific operational segments for different access technologies or customer tiers.

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: 442 networks and 1,772 prefixes, as published 2026-10-15. 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.
