AI analysis

251.137.in-addr.arpa is delegated to four name servers: ns1.fraunhofer.de, ns2.fraunhofer.de, ns3.fraunhofer.de and ns5.fraunhofer.de.

251.137.in-addr.arpa at least partially shares name servers with other domains such as key2b.sit.fraunhofer.de, ise-module-tec.de, lasercongress.com, 16.44.192.in-addr.arpa and high-eta-solarmodule.de.

These name servers are often used together with ns1.ise.fraunhofer.de, ns2.ise.fraunhofer.de, ns.iml.fraunhofer.de, ns.iis.fraunhofer.de, gate.hhi.fraunhofer.de, ns.iml.fhg.de, ns.iese.de and ns.iese.fraunhofer.de.

Host names with two IP numbers:

ns1.fraunhofer.de points to 2a03:db80:3004:d212::53:1 and 192.44.37.1

ns2.fraunhofer.de points to 2a03:db80:4420:b000::53:1 and 153.96.1.1
