Summary

ER-Telecom Holding (Bryansk)

Russian Federation · AI-generated

residential isp russia bryansk

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

What it's used for

  • The address space carries residential broadband traffic, evidenced by netnames such as ERTH-BRYANSK-DYNAMIC-PPPOE-NET and ERTH-BRYANSK-PPPOE-5-NET, and reverse DNS entries like 178x75x16x0.dynamic.bryansk.ertelecom.ru and 109x194x7x255.static-customer.bryansk.ertelecom.ru.
  • The AS announces 81,152 IPv4 addresses across 45 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 subscriber eyeballs for residential internet and television services in the Bryansk region, as indicated by the bks-tv.ru reverse DNS records and the operator's status as a regional ISP.

Notable

  • All registrants in the evidence pack are consistent with the announcer, listing "JSC 'ER-Telecom Holding'" or its Bryansk branch.
  • The address inventory is finely subdivided into numerous /21 and /22 blocks, reflecting site-by-site segmentation for different customer pools or service types within the regional network.

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: 431 networks and 1,768 prefixes, as published 2026-10-12. 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.
