Russian Federation · AI-generated

residential isp russia barnaul

The AS handle BARNAUL-AS is held by JSC "ER-Telecom Holding".

What it's used for

  • The address space carries residential broadband traffic, evidenced by reverse DNS entries such as dynamic.barnaul.ertelecom.ru, pppoe.barnaul.ertelecom.ru, and tomtelnet.ru.
  • With 66,304 IPv4 addresses announced across 52 prefixes and only 1 observed neighbour, the network functions as a local access provider rather than a transit hub.
  • Traffic consists of subscriber eyeballs for the Barnaul region, utilizing PPPoE and dynamic IP allocation for end-user devices.

Notable

  • Registrants consistently identify JSC "ER-Telecom Holding" and its Barnaul branch, aligning with the announcer.
  • The inventory is finely subdivided into /20, /21, and /22 blocks, reflecting site-by-site segmentation for a regional ISP.
  • The AS was first seen in routing tables in 2010, indicating a relatively recent establishment in the global routing table.

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 1,771 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.
