M-Root DNS Server

M.ROOT-SERVERS.NET started its operational in Aug 1997 in Tokyo, JAPAN by WIDE Project. It was the only Root DNS Server operational in the west of the Pacific Ocean until Jan 2002 when global anycast is started to deploy in the Root DNS servers. Our service IP addresses are 202.12.27.33 and 2001:dc3::35 respectively, and the routing information covering these addresses is announced from AS7500 regardless of the versions of IP. M-Root has been offering IPv6 service since February in 2008, and currently all M-Root anycast clusters offering IPv6 services.

Currently M-Root server is operated jointly by WIDE Project and Japan Registry Services Co., Ltd. (JPRS), a company running .JP ccTLD registry, under responsibility of WIDE Project.

Each cluster of M-Root server system consists of a few active servers for enhancing performance and redundancy.

ICANN Root Server System Advisory Committee (RSSAC) has published RSSAC001, which describes service expectations of Root Servers. This document describes the status of how M-Root server meets the each item of expectations stated in RSSAC001.

M-Root is currently using BIND Version 9 developed by Internet Systems Consortium. DNS software and operating system is selected based on functionality, stability, performance, diversity in ithe Root DNS servers system, and other factors.

Following traffic information includes queries over the all M-Root clusters. The time is represented in JST (UTC+09), and drawing is delayed by several hours. Blue lines indicate the inbound traffic while green areas indicate the outbound traffic.
