Analysis

IP Addresses

cbrain.de points to a single IP number: 217.160.0.254.

Additional host names — norbertp.de, imglas.de, api-ug.de and two others — share IP numbers with cbrain.de.

Name Servers

cbrain.de has four authoritative name servers: ns1112.ui-dns.biz, ns1112.ui-dns.com, ns1112.ui-dns.de and ns1112.ui-dns.org.

There is at least partial name server overlap between cbrain.de and other domains — barkey.biz, cheflifefoods.com, rauriser.at and two more among them.

These name servers regularly appear alongside ns1088.ui-dns.com, ns1030.ui-dns.de, ns1103.ui-dns.org and 5 other name servers in NS record sets.

All four hostnames — ns1112.ui-dns.biz, ns1112.ui-dns.com, ns1112.ui-dns.de and ns1112.ui-dns.org — resolve to two IP numbers apiece: ns1112.ui-dns.biz to 185.132.33.112 and 2607:f1c0:fe:53:185:132:33:112; ns1112.ui-dns.com to 185.132.34.112 and 2607:f1c0:fe:53:185:132:34:112; ns1112.ui-dns.de to 185.132.32.112 and 2607:f1c0:fe:53:185:132:32:112; ns1112.ui-dns.org to 185.132.35.112 and 2607:f1c0:fe:53:185:132:35:112.

Mail Servers

cbrain.de has two mail servers: mx00.ionos.de and mx01.ionos.de.

cbrain.de shares the same mail server setup as other domains, including premiumtierfutter.de, aixlife.de, shopid.net and two others.

cbrain.de and other domains — baupo.com for instance — share at least some mail servers.

The two host names mx00.ionos.de and mx01.ionos.de each have a pair of IP addresses: mx00.ionos.de has 212.227.15.41 and 212.227.15.171, and mx01.ionos.de has 212.227.15.188 and 217.72.192.67.
