Analysis

Name Servers

tec-observer.de is delegated to three name servers hydrogen.ns.hetzner.com, oxygen.ns.hetzner.com and helium.ns.hetzner.de.

tec-observer.de at least partially shares name servers with other domains, for instance unicoach.de, eingezogene-brustwarzen.de, feelyou.com, brille-48.de and tdtennis.de.

These name servers are commonly used with ns1.your-server.de and ns1.first-ns.de.

Host names with two IP numbers:

hydrogen.ns.hetzner.com points to 2a01:4f8:0:1::add:1098 and 213.133.100.98; oxygen.ns.hetzner.com points to 2a01:4f8:0:1::add:2992 and 88.198.229.192; helium.ns.hetzner.de points to 2001:67c:192c::add:5 and 193.47.99.5.

Mail Servers

tec-observer.de is handled by a single mail server, mail.tutanota.de.

tec-observer.de uses the same mail server setup as other domains, for instance leverstone.com, sweetman.me, casno.lv, nfora.com and z0c.de.

mail.tutanota.de points to three IP numbers: 185.205.69.211, 185.205.69.213 and 185.205.69.214.
