There is at least partial name server overlap between htdr.com and other domains — superjer.net, singledate.social, homeaidlabs.com and two more among them.

Each of the hostnames ns1.dnsowl.com, ns2.dnsowl.com and ns3.dnsowl.com directs to four IP numbers. ns1.dnsowl.com has IP addresses 162.159.26.136, 162.159.27.173, 2400:cb00:2049:1::a29f:1a88 and 2400:cb00:2049:1::a29f:1bad. ns2.dnsowl.com has IP addresses 162.159.26.49, 162.159.27.130, 2400:cb00:2049:1::a29f:1a31 and 2400:cb00:2049:1::a29f:1b82. ns3.dnsowl.com has IP addresses 162.159.26.234, 162.159.27.98, 2400:cb00:2049:1::a29f:1aea and 2400:cb00:2049:1::a29f:1b62.

Mail Servers

Five mail servers handle htdr.com: aspmx.l.google.com, alt1.aspmx.l.google.com, alt2.aspmx.l.google.com and two others.

At least some of the mail servers used by htdr.com are shared with other domains: townecenterhealth.com, rsoules.com, topliss.co.nz and two others among them.

These mail servers are often deployed together with alt3.aspmx.l.google.com, alt4.aspmx.l.google.com, aspmx2.googlemail.com and 3 other mail servers.
