About this network

JPRS-NAYUTA is the autonomous system for Japan Registry Services Co., Ltd., the organization responsible for managing the .jp domain name registry.

What it's used for

• The address space carries registry infrastructure, evidenced by the netname JPRS-NAYUTA-CIDR-BLK-JP and the registrant Japan Network Information Center; IRT-JPNIC-JP.
• The AS announces a single IPv4 prefix (203.119.40.0/24) and one IPv6 prefix (2001:dc9::/32), totaling 256 IPv4 addresses. With 13 observed neighbours, the ratio of small address inventory to moderate peering suggests a specialized infrastructure role rather than a large-scale access or transit provider.

Notable

• The registrant Japan Network Information Center; IRT-JPNIC-JP aligns with the announcer, confirming the space is held by the national registry authority.
• The address inventory is compact, consisting of one /24 block and a single /32 IPv6 prefix, which is typical for a registry operator's internal systems and public-facing services.
