Four name servers handle the delegation for triangle.net: ns1.surfnet.nl, ns2.surfnet.nl, ns3.surfnet.nl and ns1.zurich.surf.net.

There is at least partial name server overlap between triangle.net and other domains โ€” 105.145.in-addr.arpa, universiteitleiden.nl, geneticavanstotteren.nl and two more among them.
