Four name servers handle the delegation for techknowb.com: ns-cloud-a1.googledomains.com, ns-cloud-a2.googledomains.com, ns-cloud-a3.googledomains.com and ns-cloud-a4.googledomains.com.

The name servers of techknowb.com overlap at least partially with those of other domains β€” among them notademocracy.com, mypistons.com, zypsmedia.com and two more.

Each of the four hosts ns-cloud-a1.googledomains.com, ns-cloud-a2.googledomains.com, ns-cloud-a3.googledomains.com and ns-cloud-a4.googledomains.com has two IP addresses. ns-cloud-a1.googledomains.com points to 216.239.32.106 and 2001:4860:4802:32::6a. ns-cloud-a2.googledomains.com points to 216.239.34.106 and 2001:4860:4802:34::6a. ns-cloud-a3.googledomains.com points to 216.239.36.106 and 2001:4860:4802:36::6a. ns-cloud-a4.googledomains.com points to 216.239.38.106 and 2001:4860:4802:38::6a.

mxa.mailgun.org directs to 34.36.182.139, as does mxb.mailgun.org β€” both hostnames resolve to that one IP address.

mxa.mailgun.org along with mxb.mailgun.org each resolve to 34.36.182.139 IP addresses.
