Summary

NEO-TELEKOM

Russian Federation · AI-generated

residential isp russia

SV3-AS is operated by NEO-TELEKOM Ltd, a telecommunications provider based in Simferopol, Russia.

What it's used for

  • The address space carries dynamic residential traffic, as indicated by reverse DNS entries such as 91-241-136-0-dyn.neotele.com.ru and netnames registered to NEO-TELEKOM Ltd.
  • The AS announces 8704 IPv4 addresses across 2 prefixes with only 2 observed routing neighbours, a ratio characteristic of an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for the local region, consistent with the operator's role as a regional ISP.

Notable

  • Registrants for both announced prefixes (91.241.128.0/19 and 91.194.238.0/23) are listed as NEO-TELEKOM Ltd, matching the AS holder.
  • The address inventory is composed of two distinct IPv4 blocks, with no IPv6 prefixes currently announced.

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: 443 networks and 1,784 prefixes, as published 2026-10-19. 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.
