isp residential russia krasnodar

KRASNODAR-RN-INFORM-AS is operated by Siberian Internet Company LLC.

What it's used for

  • The address space carries residential or small-business internet access, indicated by the netname RN-INFORM_KRASNODAR and reverse DNS entries like ptr-64.23krd.ru and ptr-127.23krd.ru.
  • The AS announces a single IPv4 prefix, 109.236.250.0/24, comprising 256 addresses, with no IPv6 prefixes in inventory.
  • With only 2 observed neighbours, the low neighbour-to-address ratio suggests an access or eyeball network rather than a transit provider.
  • Traffic from this AS consists of subscriber internet access for the Krasnodar region, consistent with the operator's role as a local internet service provider.

Notable

  • The RDAP registrant for the announced prefix is listed as Abuse-C Role, which aligns with the announcer's identity as a local ISP branch.
  • The address inventory is minimal, consisting of a single /24 block, which is typical for a regional access provider with limited 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: 443 networks and 1,779 prefixes, as published 2026-10-24. 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.
