Russian Federation · AI-generated

residential isp penza ertelecom

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

What it's used for

  • The address space carries dynamic residential subscriber traffic, evidenced by reverse DNS entries such as 37x113x36x0.dynamic.penza.ertelecom.ru and dynamicip-94-181-132-0.pppoe.penza.ertelecom.ru.
  • The AS announces 48,640 IPv4 addresses across 32 prefixes and 1 IPv6 prefix, while maintaining only 1 observed routing neighbour, a ratio indicative of an access network rather than a transit provider.
  • Traffic consists of broadband subscriber connections for the Penza region, with some space also serving the Irkutsk region as indicated by 109x194x244x0.dynamic.irkutsk.ertelecom.ru records.

Notable

  • Registrants consistently identify the holder as JSC "ER-Telecom Holding" or its Penza Branch, aligning with the AS announcer.
  • The inventory is finely subdivided into /21 and /22 blocks, reflecting site-by-site segmentation for a large regional ISP 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 1,781 prefixes, as published 2026-10-16. 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.
