Russian Federation · AI-generated

individual ipv4 small

The AS handle CHYUS-NET-1 is held by Cherkasov Yuriy Sergiyovuch.

What it's used for

  • The address space carries the netname CHYUS-NET associated with the individual registrant.
  • The network announces 256 IPv4 addresses across 1 prefix (91.225.41.0/24) with 0 IPv6 prefixes.
  • With 2 observed neighbours, the low neighbour count relative to the single /24 block suggests a small-scale access or endpoint network rather than a transit provider.

  • The RDAP registrant Cherkasov Yuriy Sergiyovuch matches the registry holder and AS name.
  • The address inventory consists of a single contiguous /24 block in the Russian Federation.

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: 446 networks and 1,852 prefixes, as published 2026-10-27. 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.
