About this network

AS17678 is operated by Wind Gunma Internet Co., Ltd.

What it's used for

• The address space is registered under the netname JPNIC-NET-JP with the Japan Network Information Center, indicating standard Japanese ISP allocation.
• The AS announces 8192 IPv4 addresses across 2 prefixes and 1 IPv6 prefix, while maintaining only 1 observed neighbour, a ratio characteristic of a small access or eyeball network rather than a transit provider.

Notable

• The registrants for both announced IPv4 prefixes are listed as the Japan Network Information Center, which is the national registry rather than the operating company, a common structure for Japanese ISPs.
• The inventory consists of two /20 blocks and a single /32 IPv6 prefix, representing a modest address estate typical of a regional internet service provider.
