Summary

Svyaz-Energo

Russian Federation · AI-generated

isp residential russia

SV-EN-AS is operated by Svyaz-Energo Ltd.

What it's used for

  • The address space carries residential and access traffic, evidenced by netnames like SVEN-Users and reverse DNS entries such as access-178-57-59-255.kmtn.ru and 254-117-19-46.sv-en.ru.
  • The AS announces 20,480 IPv4 addresses across 18 prefixes and 1 IPv6 prefix, while maintaining only 9 observed neighbours. This high address-to-neighbour ratio indicates an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber eyeballs, specifically residential internet users connected via the operator's access infrastructure.

Notable

  • Registrants are consistent with the announcer, primarily listing Svyaz-Energo Ltd. and Kmtn NOC, with one prefix registered to Aksioma Ltd.
  • The address inventory is fragmented into multiple /21, /22, /23, and /24 blocks, suggesting a history of incremental allocation or acquisition of address space.

Reputation

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 1,773 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.
