About this network

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.
