Summary

CROC

Russian Federation · AI-generated

business it corporate

The AS handle CROC-AS is held by CROC, a Russian technology company.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname PI-CROC-NET and registrant "CROC DC operations group".
  • The inventory consists of 256 IPv4 addresses within a single /24 prefix (195.38.23.0/24) and 0 IPv6 prefixes. With only 2 observed neighbours, this small, isolated footprint indicates an internal corporate estate rather than a transit or access network.

Notable

  • The RDAP registrant "Closed Joint Stock Company CROC incorporated" aligns perfectly with the AS holder and the netname, confirming consistent ownership.
  • CROC is a well-established Russian IT services provider founded in 1992, operating in the technology market.
  • The address inventory is a single contiguous /24 block, typical for a corporate site or data center segment.

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 1,782 prefixes, as published 2026-10-16. 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.
