About this network

RELNET is operated by RELATION Co., Ltd.

What it's used for

• The address space carries residential and access traffic, indicated by the PeeringDB classification as a Cable/DSL/ISP and the netname RELATION-CIDR-BLK-JP.
• The AS announces 4096 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, with 5 observed neighbours; this ratio suggests an access or eyeball network rather than a transit provider.

Notable

• Registrants for both IPv4 prefixes are listed as Japan Network Information Center; IRT-JPNIC-JP, which is the regional registry rather than the end-user, consistent with standard JPNIC allocation practices.
• The inventory consists of two /21 blocks in the 202.142.8.0 and 203.99.224.0 ranges, plus a /32 IPv6 prefix, representing a modest footprint typical of a regional ISP.
