Summary

ER-Telecom Holding

Russian Federation · AI-generated

residential isp russia broadband

The AS handle SPB-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 5x164x80x0.dynamic.spb.ertelecom.ru and dynamicip-188-187-95-255.pppoe.volgograd.ertelecom.ru.
  • The AS announces 123,392 IPv4 addresses across 43 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio indicative of an access network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs for fixed-line internet access, primarily in the Saint Petersburg and Volgograd regions of Russia.

Notable

  • All registrants align with the announcer, consistently listing JSC "ER-Telecom Holding" or its Saint Petersburg branch.
  • The address inventory is finely subdivided into numerous /19, /20, and /21 blocks, reflecting site-by-site segmentation for a large regional ISP.

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: 436 networks and 1,771 prefixes, as published 2026-10-13. 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.
