About this network

AS38631 is operated by LY Corporation.

What it's used for

• The address space carries infrastructure for LY Corporation's digital services, with netnames explicitly labeled LY and LINE in the RDAP records.
• The AS announces 108,288 IPv4 addresses across 44 prefixes and 123 IPv6 prefixes, while maintaining 29 observed neighbours; this ratio of substantial address inventory to a moderate peer count indicates a large-scale business network rather than a transit provider.
• Traffic from this AS consists of web and API endpoints for LY Corporation's consumer-facing platforms, including the LINE messaging application and Yahoo Japan search and e-commerce services.

Notable

• Registrants for the largest prefixes are consistently listed as Japan Network Information Center with IRT contact IRT-JPNIC-JP, aligning with the AS holder identity.
• LY Corporation was formed in October 2023 through the reorganization of LINE Corporation and Yahoo Japan Corporation, which explains the dual LINE and LY netnames present in the inventory.
• The inventory is dominated by large blocks in the 43.223.0.0/16 and 147.92.128.0/16 ranges, reflecting a consolidated corporate estate.
