Analysis

Name Servers

The domain simtk.net is delegated to these four name servers: ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com and ns-cloud-e4.googledomains.com.

simtk.net has at least partial name server overlap with other domains, such as attainplatform.com, laz-i.com, henisland.net and two others.

ns-cloud-e1.googledomains.com, ns-cloud-e2.googledomains.com, ns-cloud-e3.googledomains.com and ns-cloud-e4.googledomains.com all point to exactly two IP numbers each: ns-cloud-e1.googledomains.com → 216.239.32.110 and 2001:4860:4802:32::6e; ns-cloud-e2.googledomains.com → 216.239.34.110 and 2001:4860:4802:34::6e; ns-cloud-e3.googledomains.com → 216.239.36.110 and 2001:4860:4802:36::6e; ns-cloud-e4.googledomains.com → 216.239.38.110 and 2001:4860:4802:38::6e.

Mail Servers

simtk.net is handled by five mail servers: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com and two others.

simtk.net shares at least some of its mail servers with other domains — for example mavd.nl, anjoo.de, pakya.com and two more.

It is common to find these mail servers paired with mail servers alt4.aspmx.l.google.com, alt3.aspmx.l.google.com, aspmx2.googlemail.com and 3 more.

Hosts with two IP numbers each:

aspmx.l.google.com directs traffic to 172.253.122.26 and 2607:f8b0:4004:c09::1a.

alt1.aspmx.l.google.com directs traffic to 108.177.123.27 and 2800:3f0:4003:c0f::1a.

alt2.aspmx.l.google.com directs traffic to 172.253.116.26 and 2a00:1450:400b:c02::1b.

alt3.aspmx.l.google.com directs traffic to 192.178.223.27 and 2a00:1450:4009:c0f::1b.

alt4.aspmx.l.google.com directs traffic to 172.253.157.26 and 2a00:1450:400c:c23::1a.
