Analysis

IP Addresses

stui.com points to a single IP number: 178.20.100.251.

Additional host names — stui-soundandlight.de, server1.howitworks.de, howitworks.de and two others — share IP numbers with stui.com.

Name Servers

stui.com is served by three name servers: cns2.cloudpit.com, cns1.cloudpit.de and cns3.cloudpit.io.

stui.com partially shares its NS delegation with several other domains, including cges.de, tanzmusikduo.de, adler-apotheke.ch and two others.

These name servers regularly co-occur with the name servers ns1.namesrv.ch, ns3.namesrv.io and ns2.namesrv.net.

The hostnames cns2.cloudpit.com, cns1.cloudpit.de and cns3.cloudpit.io each direct to two IP addresses — cns2.cloudpit.com to 148.251.254.105 and 2a01:4f8:2b02:a88::105, cns1.cloudpit.de to 109.237.142.8 and 2a01:64c0:0:5000::8, and cns3.cloudpit.io to 109.237.143.8 and 2a02:2b80:101:5000::8.

Mail Servers

stui.com has two mail servers: mx03.secure-mailgate.com and mx04.secure-mailgate.com.

stui.com shares the same mail server setup as other domains, including boier.fi, luftballon-chemnitz.de, trendcom.at and two others.

mx03.secure-mailgate.com resolves to 46.243.88.174 and 46.243.88.176. Likewise, mx04.secure-mailgate.com resolves to 46.243.88.175 and 46.243.88.177 — two IP addresses apiece.
