About this network

NNS is the AS handle for Nihon Network Service Co., Ltd., a Japanese network operator.

What it's used for

• The address space carries corporate and network infrastructure, evidenced by reverse DNS names such as nns.ne.jp, ccnetptb..nns.ne.jp, and ubr04b254.nns.ne.jp.
• The AS announces 38,912 IPv4 addresses across 4 prefixes and 1 IPv6 prefix, with only 1 observed neighbour, indicating a small, self-contained internal corporate estate rather than a large access or transit network.

Notable

• All registrants for the announced prefixes are listed as Japan Network Information Center with the netname CCNET or CCNET-CIDR-BLK-JP, which aligns with the operator's historical association with the CCNET (Computer Center Network) infrastructure in Japan.
• The address inventory consists of four distinct IPv4 blocks, including two /18s, one /20, and one /21, along with a single /32 IPv6 prefix, reflecting a finely subdivided internal allocation.
