Summary

LCV Corporation

Japan · AI-generated

business japan corporate

The AS handle LCV is held by LCV Corporation.

What it's used for

  • The address space carries corporate infrastructure, evidenced by the netname LCV-CIDR-BLK-JP across all announced prefixes and reverse DNS entries like sg-c04-0255.lcv.ne.jp and www2.sacs.co.jp.
  • The AS announces 51,200 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, with only 2 observed neighbours, indicating a small, self-contained corporate network rather than a transit or access provider.

Notable

  • All registrants are listed as Japan Network Information Center with the IRT contact IRT-JPNIC-JP, which is standard for Japanese IP allocations and does not indicate a mismatch with the announcer.
  • The inventory consists of six distinct IPv4 blocks ranging from /17 to /21, all under the single netname LCV-CIDR-BLK-JP, suggesting a consolidated corporate estate.

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 1,783 prefixes, as published 2026-10-20. 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.
