Russian Federation · AI-generated

russia small ipv4

The AS handle NSK-LLCFLEX-AS is held by LLC Flex.

What it's used for

  • The address space is registered under the netname RU-CLOUD4Y-20140409, indicating usage associated with cloud or hosting services.
  • The network announces 256 IPv4 addresses within a single /24 prefix (185.53.106.0/24) and has 1 observed routing neighbour.
  • The low neighbour count relative to the address block suggests a small-scale network, possibly for specific service delivery or internal use rather than broad transit.

Notable

  • The registrant LLC Flex matches the AS holder name NSK-LLCFlex-AS LLC Flex.
  • The inventory consists of a single contiguous /24 block with no IPv6 prefixes 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: 453 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.
