Analysis

IP Addresses

eclass.io directs to four IP numbers, which are 104.21.36.229, 172.67.200.201, 2606:4700:3032::6815:24e5 and 2606:4700:3033::ac43:c8c9.

yongxunjiechongzhiewinyulecheng.xf.xcfamily.com, huangguanbeiyongtouzhuwang.xf.xcfamily.com, w9ogl.xcfamily.com plus two other host names have IP numbers in common with eclass.io.

Name Servers

eclass.io is delegated to two name servers: carol.ns.cloudflare.com and dan.ns.cloudflare.com.

The name server configuration of eclass.io is shared with other domains, for instance northtoalaska.com, thecannoncenter.com, mediasd.com and two others.

The name servers of eclass.io overlap at least partially with those of other domains — among them mailcookie.com, antalyaredescort.xyz, esindustrial.net and two more.

Hosts with 6 IP addresses each:

carol.ns.cloudflare.com resolves to 108.162.192.80, 172.64.32.80, 173.245.58.80 and 3 other IP addresses.

dan.ns.cloudflare.com resolves to 108.162.193.108, 172.64.33.108, 173.245.59.108 and 3 other IP addresses.

Mail Servers

Five mail servers handle eclass.io: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com and two others.

At least some of the mail servers used by eclass.io are shared with other domains: lauraalunni.com, tharseogroup.com, ns500758.ns500759.ns500758.ns500759.ns500736.ns500735.ns500698.ns500735.ns500698.ns500698.ns500708.ns500708.ns500708.ns500576.ns500619.ns500652.ns500619.trackreceptor.com and two others among them.

These mail servers are often deployed together with alt3.aspmx.l.google.com, alt4.aspmx.l.google.com, aspmx2.googlemail.com and 3 other mail servers.

Host names pointing to two IP addresses:

aspmx.l.google.com points to 64.233.180.27 and 2607:f8b0:4004:c1d::1b.

alt1.aspmx.l.google.com points to 192.178.234.27 and 2800:3f0:4003:c14::1b.
