M.ROOT-SERVERS.NET has been operational since
Aug 1997 in Tokyo, JAPAN by
It was the only Root DNS Server operational in the west of the Pacific Ocean
until Jan 2002 and large number of DNS servers especially in Asia-Pacific region
are sending queries to M-Root.
Our service IP addresses are 184.108.40.206 and 2001:dc3::35
respectively, and the routing information covering these addresses is
announced from AS7500 regardless of the versions of IP.
There are anycast servers of M-Root, 3 clusters
in Tokyo (JP),
2 clusters in Paris (FR), and one cluster each in
Osaka (JP), Seoul (KR), and
San Francisco, CA (US).
M-Root is one of the 7 Root DNS servers offering service in IPv6
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 JPRS, a company running .JP ccTLD registry, under responsibility of WIDE Project.
WIDE Project and JPRS, jointly operating "M" root DNS nameserver, recognize the following organizations as current root nameserver operators and endeavors to coordinate operational service with them.

Each cluster of M-Root server system consists of a few active servers for enhancing performance and redundancy. These servers are connected to three independent major internet exchanges -- DIX-IE (former NSPIXP-2), JPIX, and JPNAP in Tokyo (JP). In Osaka (JP), it touches down at NSPIXP-3, JPNAP-Osaka, and JPIX-Osaka. In Seoul (KR), it is connected to KINX. In San Francsico, CA (US), it is connected to SFMIX and AMS-IX Bay Area. In Paris (FR), it is connected to SFINX, PARIX, Equinix Paris, NL-ix, JointTransit, as well as France-IX.
Numbers of ISPs are peering with M-Root and some of them are providing free transit service for M-Root. This configuration provides no single point of failure except for the highly reliable power supply system (with battery and generator in the case of outage of the commercial power supply) of the datacenter where the server system is colocated.
Effective on 1705 UTC of Feb 4, 2008, the IPv6 service of M-Root has started with its address 2001:dc3::35. The IPv6 services is offered by all M-Root clusters currently. The traffic density of IPv6 queries are about 10% out of 30kqps traffic in May 2017.
Following traffic information includes queries over the all M-Root clusters. The time is represented in JST (UTC+09), and drawing is delayed for several hours. Blue lines indicate the inbound traffic while green areas indicate the outbound traffic.
M Root DNS Server in Seoul, Korea has been operational since Jul. 21, 2004. It has been supported extensively by KINX, Korea Internet Neutral eXchange.
