residential isp tver voip

TVER-AS is operated by JSC "ER-Telecom Holding".

What it's used for

  • The address space carries residential broadband and VoIP traffic, evidenced by reverse DNS entries such as dynamic.tver.ertelecom.ru and pppoe.tver.ertelecom.ru, as well as the netname ERTH-TVER-VOIP-1-NET.
  • The AS announces 23,296 IPv4 addresses across 8 prefixes and 10 IPv6 prefixes, while maintaining only 1 observed neighbour, a ratio characteristic of an access network serving end-users rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs and VoIP media/signalling for the Tver region, consistent with ER-Telecom's role as a regional telecommunications operator.

Notable

  • Registrants for the largest prefixes are consistent with the announcer, listing JSC "ER-Telecom Holding" and its Tver' Branch, with one prefix also referencing Enforta HQ.
  • The address inventory is finely subdivided into multiple /20, /21, and /24 blocks, reflecting site-by-site segmentation within the corporate 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: 452 networks and 1,853 prefixes, as published 2026-11-05. 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.
