Analysis

IP Addresses

open5gcore.net points to a single IP: 153.97.176.206.

Other host names, for instance itbms.org, www.iml4e.org, innovaccess.eu, projekt-biflex.de and ecn-online.com share IP numbers with open5gcore.net.

Name Servers

open5gcore.net is delegated to three name servers: x.ns.joker.com, y.ns.joker.com and z.ns.joker.com.

open5gcore.net at least partially shares its name servers with other domains, for instance karagis.com, demoefekti.net, hundesalon-tulln.at, koledo.com and leatherfans.com.

These name servers are commonly used with a.ns.joker.com, b.ns.joker.com and c.ns.joker.com.

Host names with two IP numbers: The host name y.ns.joker.com points to 2a01:4f8:c0c:165b::1 and 23.88.49.189; The host name z.ns.joker.com points to 2607:5300:203:7e6d::2222 and 192.95.37.184.

Host names with one IP number: The host name x.ns.joker.com points to 194.245.103.13.

Mail Servers

open5gcore.net is handled by four mail servers: edge01.mx.fraunhofer.de, edge02.mx.fraunhofer.de, edge03.mx.fraunhofer.de and edge04.mx.fraunhofer.de.

open5gcore.net shares some mail servers with other domains, including agrivoltaicsmap.ise.fhg.de, pv-performance.org, nc1.ise.fhg.de, planning-bipv.com and freiburg.fraunhofer.de.

Twelve IP numbers per name:

edge01.mx.fraunhofer.de points to 2a03:db80:4420:b000::25:242a03:db80:4420:b000::25:272a03:db80:4420:b000::25:30153.96.1.24153.96.1.27153.96.1.30192.102.154.218192.102.154.220192.102.154.221192.102.163.124192.102.163.195 and 192.102.163.204.

edge02.mx.fraunhofer.de points to the same set.

edge03.mx.fraunhofer.de points to the same set.

edge04.mx.fraunhofer.de points to the same set.
