Russian Federation · AI-generated

residential isp chelyabinsk ertelecom

The AS handle ERTH-CHEL-AS is held by JSC "ER-Telecom Holding", specifically its Chelyabinsk branch.

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by reverse DNS names such as dynamicip-.pppoe.chel.ertelecom.ru and .static-business.chel.ertelecom.ru.
  • The network announces 43,776 IPv4 addresses across 16 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a local access network rather than a transit provider.
  • Traffic consists of broadband subscriber connections (PPPoE) and static business IPs for customers in the Chelyabinsk region.

Notable

  • Registrants consistently identify JSC "ER-Telecom Holding" or its Chelyabinsk branch, aligning with the AS holder.
  • The inventory includes netnames like ERTH-CHEL-PPPOE-11-NET and ERTH-CHEL-NET-CORP, reflecting segmentation for different service types and corporate use.
  • The address inventory is dominated by the 95.78.128.0/19 block, with smaller allocations in 37.113.0.0/16 and 94.181.0.0/16.

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.
