mixhostのDNSサーバをホストしているのはどこ?

Posted at

ヘルプは場所まで

ns1.mixhost.jp - 東京
ns2.mixhost.jp - 九州
ns3.mixhost.jp - 北海道
ns4.mixhost.jp - 東京
s5.mixhost.jp - 東京

ネームサーバーは冗長化されていますか? | mixhostヘルプセンター

ドメインを正引き~

nslookup
ns1.mixhost.jp > 104.198.116.63
ns2.mixhost.jp > 210.152.15.180
ns3.mixhost.jp > 153.127.195.29
ns4.mixhost.jp > 54.65.133.78
ns5.mixhost.jp > 104.198.92.250

IPを逆引き~

nslookup
104.198.116.63 > 63.116.198.104.bc.googleusercontent.com
210.152.15.180 > 210-152-15-180.jp-west.compute.idcfcloud.com
153.127.195.29 > 153.127.195.29
54.65.133.78 > ec2-54-65-133-78.ap-northeast-1.compute.amazonaws.com
104.198.92.250 > 250.92.198.104.bc.googleusercontent.com

ns3 だけ逆引きが設定されていない。
北海道といえばさくらインターネットの石狩データセンター。
多分合ってるけど、一応traceroute

(略)
16	59.128.9.74		153.199											Japan
17	103.10.113.122	153.170		iskrt2s-rt4.bb.sakura.ad.jp			Japan
18	103.10.113.50	153.143		sac-is1b-rt1-rt101b.bb.sakura.ad.jp	Japan
19	153.127.195.29	153.053											Japan

結果

  • ns1.mixhost.jp - Google Cloud Platform
  • ns2.mixhost.jp - IDCFクラウド
  • ns3.mixhost.jp - さくらのクラウド
  • ns4.mixhost.jp - AWS(Amazon Web Services)
