About this network

The AS handle YAHOO is held by LY Corporation.

What it's used for

• The address space carries corporate infrastructure for a major Japanese internet portal, evidenced by the consistent netname YAHOO-NET across all announced prefixes.
• The AS announces 66,560 IPv4 addresses across 7 prefixes and 1 IPv6 prefix, while maintaining 24 observed neighbours. This ratio of moderate address space against a significant number of peers indicates a large-scale business network with substantial peering requirements rather than a pure transit provider.

Notable

• All RDAP registrants for the largest prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which aligns with the Japanese origin of the operator and the YAHOO-NET netnames.
• LY Corporation was formed in October 2023 through the reorganization of Group companies including LINE Corporation and Yahoo Japan Corporation, consolidating their digital assets under a single corporate entity.
• The inventory consists of seven distinct IPv4 blocks ranging from /17 to /22 sizes, alongside a single /32 IPv6 prefix, reflecting a segmented corporate estate.
