Russian Federation · AI-generated

residential isp russia pppoe

VORONEZH-AS is operated by JSC "ER-Telecom Holding".

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by reverse DNS entries such as dynamic.izhevsk.ertelecom.ru, static-business.voronezh.ertelecom.ru, and pppoe.voronezh.ertelecom.ru.
  • The AS announces 38,656 IPv4 addresses across 26 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour, a ratio characteristic of an access network rather than a transit provider.
  • Traffic consists of broadband subscriber eyeballs and static business endpoints for the ER-Telecom regional ISP operations in Voronezh, Izhevsk, and Ufa.

Notable

  • Registrants consistently identify JSC "ER-Telecom Holding" and its Voronezh Branch, aligning with the AS handle and the operator's identity.
  • The inventory is finely subdivided into numerous /20, /21, /22, and /24 blocks, reflecting site-by-site segmentation for different access technologies and geographic zones within the corporate estate.

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 1,783 prefixes, as published 2026-10-17. 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.
