About this network

MEI1 is operated by Panasonic Information Systems Co., Ltd.

What it's used for

• The address space carries corporate infrastructure, evidenced by netnames such as PANA-NET and PANA-NET-CIDR-BLK-JP associated with the registrant IRT-JPNIC-JP.
• The AS announces 383232 IPv4 addresses across 50 prefixes, while maintaining only 1 observed neighbour, a ratio that indicates an internal corporate estate rather than a transit or access network.

Notable

• Registrants for the largest prefixes include IRT-JPNIC-JP and Japan Network Information Center, which align with the announcer's identity as a Japanese corporate entity.
• The address inventory is finely subdivided into multiple /16, /18, /19, /20, and /21 blocks, reflecting site-by-site segmentation typical of a large multinational corporation.
