About this network

The AS handle E-DNS-JP is held by the WIDE Project.

What it's used for

• The AS announces 256 IPv4 addresses and 1 IPv6 prefix, with 5 observed neighbours, indicating a specialized infrastructure role rather than a transit or access provider.

Notable

• The registrant for the announced prefix is the Japan Network Information Center (JPNIC), which is consistent with the WIDE Project's role as a Japanese research and infrastructure organization.
• The WIDE Project is a long-standing Japanese Internet research initiative founded by Keio University, Tokyo Institute of Technology, and The University of Tokyo, known for its contributions to Internet infrastructure and the operation of the M-Root DNS Server.
• The address inventory consists of a single /24 IPv4 block and one /35 IPv6 prefix, reflecting a focused allocation for specific infrastructure services.
