Analysis

Hierarchy

The parent of www.cdt.org is cdt.org.

IP Addresses

cdt.org resolves to two IP numbers: 172.66.133.113 and 172.66.138.228.

Other host names, such as www.cdt.org, share IP numbers with cdt.org.

Name Servers

Two name servers abby.ns.cloudflare.com and noah.ns.cloudflare.com handle delegation for cdt.org.

cdt.org uses the same name server setup as other domains, for example ktuber.com, oat.bz, kfimplant.com, kalo.ge and tasheed.org.

cdt.org partially shares name servers with other domains; examples include craftalytics.com, avart.co, ruta.software, italyget.com and anthonypersaud.com.

These name servers commonly accompany lloyd.ns.cloudflare.com, ajay.ns.cloudflare.com, annalise.ns.cloudflare.com and magdalena.ns.cloudflare.com.

Host names with six IP numbers: abby.ns.cloudflare.com points to: 2606:4700:50::adf5:3a64, 2803:f800:50::6ca2:c064, 2a06:98c1:50::ac40:2064, 108.162.192.100, 172.64.32.100 and 173.245.58.100; noah.ns.cloudflare.com points to: 2606:4700:58::adf5:3b85, 2803:f800:50::6ca2:c185, 2a06:98c1:50::ac40:2185, 108.162.193.133, 172.64.33.133 and 173.245.59.133.

Mail Servers

Five mail servers handle cdt.org: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com, alt3.aspmx.l.google.com and alt4.aspmx.l.google.com.

cdt.org shares some mail servers with other domains, at least partially, such as greaterloveinternational.org, isamanlaw.com, ns500758.ns500698.ns500698.ns500698.ns500698.ns500735.ns500698.ns500698.ns500698.ns500698.ns500698.ns500576.ns500698.ns500576.ns500652.ns500652.ns500619.trackreceptor.com, ns500841.ns500795.ns500794.ns500795.ns500794.ns500794.ns500794.ns500795.ns500821.ns500821.ns500795.ns500790.ns500795.lustypartnersfinder.com and ns500699.ns500699.ns500693.ns500699.ns500734.ns500693.ns500612.ns500612.ns500612.ns500612.ns500588.ns500588.dtrkdll.com.

These mail servers are often used together with aspmx2.googlemail.com and aspmx3.googlemail.com.
