Summary

LY Corporation

Japan · AI-generated

business tech japan

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.

Classification and threat

Hosting Datacenter or cloud provider. Addresses are servers, not people.

Spamhaus DROP

Not on ASN-DROP The network as a whole is not listed.

No DROP prefixes None of its announced space is on the DROP prefix list.

Spamhaus DROP ("Don't Route Or Peer") lists space and networks run by, or hijacked for, spam and cybercrime operations: 431 networks and 1,775 prefixes, as published 2026-10-11. A short, high-confidence list, so a match is worth taking seriously, and absence from it says little on its own.

FBI IC3

No IC3 indicators Nothing from the FBI IC3 feed.

IC3 threat data is alpha. Absence of an indicator is not evidence of good behaviour, only of absence from this one feed.
