Name Servers
Two name servers handle the delegation for tokyo-tech.com: ns1.dns.ne.jp and ns2.dns.ne.jp.
tokyo-tech.com shares its NS records with other domains, for example standage.org, fuchucc.com, yco.jp and two others.
There is at least partial name server overlap between tokyo-tech.com and other domains — garage-base.com, hair-basil.jp, world-recycle.net and two more among them.
These name servers are routinely deployed together with the name servers master.dns.ne.jp.
ns1.dns.ne.jp → 61.211.236.1 and ns2.dns.ne.jp → 133.167.21.1: one IP number per host name.
