About this network

AIST is the autonomous system for the National Institute of Advanced Industrial Science and Technology.

What it's used for

• The address space is registered under the netname JAPAN150 with the Japan Network Information Center, indicating a national research institution's infrastructure.
• The AS announces 199,936 IPv4 addresses across 30 prefixes while maintaining only 1 observed neighbour, a ratio characteristic of a large internal corporate or institutional estate rather than a transit provider.

Notable

• All sampled registrants are listed as IRT-JPNIC-JP (Japan Network Information Center), which is consistent with the holder being a major Japanese national entity.
• The address inventory is heavily subdivided, with the majority of prefixes falling within the 150.18.0.0/16 and 150.29.0.0/16 blocks, reflecting site-by-site segmentation for a large organization.
