About this network

USEN-NET is operated by USEN Corporation, a Japanese telecommunications and broadcasting company.

What it's used for

• The address space carries corporate and content delivery infrastructure, evidenced by reverse DNS entries such as 118x238x144x0.ap118.usen.com and 125x63x36x0.rev.usen.com.
• With 20,480 IPv4 addresses announced across 2 prefixes and 12 observed neighbours, the ratio suggests a regional content or business network rather than a large-scale residential access provider.

Notable

• Registrants for both announced prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which is consistent with the announcer being a Japanese entity.
• The address inventory consists of two distinct IPv4 blocks, 118.238.128.0/18 and 125.63.32.0/20, both under the netname USEN-Corp-CIDR-BLK-JP.
