About this network

OKN is held by NTT DOCOMO BUSINESS, Inc.

What it's used for

• The space carries business and interop traffic, evidenced by the netname OKN-1-CIDR-BLK-JP and the reverse DNS entry 127-dynamic.interop.ipnw.net.
• The AS announces 256 IPv4 addresses across 1 prefix and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained network segment rather than a transit provider.
• Traffic from this AS consists of data communication and long-distance services for business users, consistent with NTT DOCOMO BUSINESS's role in providing telecommunication services for corporate clients.

Notable

• The registrant for the announced prefix is Japan Network Information Center; IRT-JPNIC-JP, which differs from the AS holder name but reflects standard JPNIC allocation practices for Japanese operators.
• The operator was previously known as NTT Communications Corporation before being renamed to NTT DOCOMO BUSINESS, Inc.
• The address inventory is minimal, consisting of a single /24 IPv4 block and a single /48 IPv6 block, typical for a specific service segment within a larger corporate estate.
