Summary

ER-Telecom Kursk

Russian Federation · AI-generated

residential isp russia pppoe

ERTH-KURSK-AS is operated by JSC "ER-Telecom Holding" Kursk Branch.

What it's used for

  • The address space carries residential and business subscriber traffic, evidenced by netnames such as ERTH-KURSK-PPPOE-15-NET and ERTH-LIPETSK-PPPOE-21-NET, and reverse DNS entries like dynamic.kursk.ertelecom.ru and static-customer.kursk.ertelecom.ru.
  • The AS announces 19,712 IPv4 addresses across 17 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, including dynamic PPPoE and static customer IPs, serving the Kursk region and surrounding areas.

Notable

  • Registrants consistently identify JSC "ER-Telecom Holding" Kursk Branch or its Network Operation Center, aligning with the AS handle and announced space.
  • The inventory includes prefixes registered to different regional branches, such as barnaul.ertelecom.ru in reverse DNS, reflecting ER-Telecom's multi-regional structure under a single holding company.
  • The address inventory is finely subdivided into /21, /22, /23, and /24 blocks, typical of a regional ISP managing distinct 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: 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.
