About this network

WAI-NET is the autonomous system for Cable Media Waiwai Co.,Ltd., a Japanese cable television and internet service provider.

What it's used for

• The address space carries residential and business access traffic, evidenced by reverse DNS entries such as n01-d-032-000.wainet.ne.jp and s03-d-144-000.wainet.ne.jp under the wainet.ne.jp domain.
• The AS announces 52,224 IPv4 addresses across 6 prefixes and 1 IPv6 prefix, maintaining 16 observed routing neighbours; this ratio of address space to peering partners indicates an access network rather than a transit provider.
• Traffic originates from subscribers using cable TV, internet, and telephone services provided by the operator in the Waiwai region of Japan.
