fs-etec.kit.edu, fs-etec.de and public.fs-etit.kit.edu are examples of other host names that share IP numbers with fsetec.de.

Name Servers

fsetec.de carries NS records delegating to ns-p-2.kit-dns.de, ns-p-1.kit-dns.eu and ns-p-3.kit-dns.net.

fsetec.de has at least partial name server overlap with other domains, such as wak-gmbh.de, uni-karlsruhe.com, phoibos.de and two others.

ns-p-2.kit-dns.de, ns-p-1.kit-dns.eu and ns-p-3.kit-dns.net are three hostnames that each resolve to a pair of IP addresses: ns-p-2.kit-dns.de to 185.237.153.53 and 2001:678:da4::53, ns-p-1.kit-dns.eu to 185.237.152.53 and 2001:678:da0::53, and ns-p-3.kit-dns.net to 141.52.0.53 and 2a00:139f:e::53.
