IP Addresses

err.ch resolves to one IP address: 49.13.125.142.

mail.higgossau.ch, mensch-marke.info, stadtwerke-gossau.ch and two other host names share IP numbers with err.ch.

Name Servers

Two name servers handle the delegation for err.ch: ns1.dnssys.ch and ns2.dnssys.ch.

err.ch uses the same name servers as several other domains — among them parm.ch, hostsys.ch, papst.ch and two more.

ns1.dnssys.ch and ns2.dnssys.ch both carry two IP addresses. The A records for ns1.dnssys.ch are 138.201.93.176 and 2a01:4f8:1c17:4ad6::1; the A records for ns2.dnssys.ch are 88.99.32.82 and 2a01:4f8:1c17:439e::1.

err.ch has at least partial mail server overlap with other domains such as finance-doc.com, goeast.com, bluemonkey.ch and two more.

mx-cluster01-hz13.hornetsecurity.ch, mx-cluster02-hz13.hornetsecurity.ch, mx-cluster03-hz13.hornetsecurity.ch and mx-cluster04-hz13.hornetsecurity.ch each point to one IP number, which is 94.100.143.100 in every case.

mx-cluster01-hz13.hornetsecurity.ch, mx-cluster02-hz13.hornetsecurity.ch, mx-cluster03-hz13.hornetsecurity.ch and mx-cluster04-hz13.hornetsecurity.ch are host names that each resolve to 94.100.143.100.
