Analysis

Hierarchy

gu.se is the parent of socwork.gu.se, gu85a-bc.gu.se, gu43d-nw.gu.se, gu83c-ex.gu.se, wmst.gu.se and hundreds of other host names.

IP Addresses

gu.se resolves to one IP number: 130.241.39.203.

Other host names, for instance forskningsdata.se, www.gu.se and k8s.gu.se share IP numbers with gu.se.

Name Servers

gu.se delegates to four name servers: ns2.chalmers.se, sunic.sunet.se, ns1.net.gu.se and ns2.net.gu.se.

gu.se at least partially shares name servers with other domains, including 251.235.130.in-addr.arpa, a.0.f.7.1.0.0.0.b.6.0.1.0.0.2.ip6.arpa, 245.36.192.in-addr.arpa, 211.108.192.in-addr.arpa and 13.71.192.in-addr.arpa.

These name servers are commonly used with ns1.chalmers.se, ns3.chalmers.se, gungner.kau.se, ymer.kau.se, nx1.ri.se, nx2.ri.se, nx3.ri.se, nx4.ri.se, gungner.dc.kau.se and ymer.dc.kau.se.

Host names with two IP numbers: ns2.chalmers.se points to 2001:6b0:2:20::1 and 129.16.253.252; sunic.sunet.se points to 2001:6b0:7::2 and 192.36.125.2; ns1.net.gu.se points to 2001:6b0:d:9600::22 and 130.241.150.34; ns2.net.gu.se points to 2001:6b0:d:25::25:13 and 130.241.25.13.

Mail Servers

A single mail server handles gu.se, gu-se.mail.protection.outlook.com.

gu.se shares the same mail server setup as other domains, for instance envmed.gu.se, med.gu.se, rel.gu.se, derm.gu.se and mednet.gu.se.

gu-se.mail.protection.outlook.com maps to four IP numbers: 52.101.68.12, 52.101.68.25, 52.101.73.8 and 52.101.73.12.
